Abstract:

Nanocrystalline yttria-stabilized zirconia (nc-Y-TZP) powders coated with 10 vol% sodium strontium silicate glass were prepared by the sol-gel method. The glass is found to uniformly coat the zirconia particles or particle aggregates. The presence of the glass was found to enhance the densification of the powder compacts leading to 97% of the theoretical density compared to 90% in the pure nc-Y-TZP. It also resulted in a fine microstructure, homogeneous particle shape, and narrow size distribution. The polyhedral-shaped faceted grains in the sintered pure Y-TZP were converted to round-shaped grains in the glass containing specimens

Abstract:

Single Bi-doped and M/Bi co-doped silicate glass (M=Al, Y, La) were prepared and broadband NIR emission were observed when the glass samples were pumped by 514 nm and 808 nm LD, respectively. The absorption intensity and emission intensity of the Y/Bi co-doped glass and La/Bi co-doped glass decrease obviously compared to single Bi-doped glass. The absorption intensity in the region of 600-1100 nm and the NIR emission intensity pumped by an 808 nm LD were remarkably enhanced by the introduction of Al2O3into the Bi-doped silicate glass. It is suggested that the Al/Bi co-doped silicate glass might be very useful for broadband fiber amplifiers and widely tunable lasers.

Abstract:

We report a new SBN-tellurite ceram-glass system, where the [(SrO)(y)(BaO)(1−y) (Nb2O5)](1−x) (SBN) ferroelectric crystallites precipitate on a tellurite (TeO2)x glass surface with nominal compositions x < 0.8 and y = 0.6 to 0.75. X-ray diffraction, calorimetry, and electro-optic measurements confirmed the ferroelectric nature of the SBN crystallites. In principle, this system has the potential for high transparency and the property tunability to match the application needs of optical devices.

Abstract:

The rare earth elements (RE= Y, Sm, La, Ce) were used as alloying materials in Cu50Zr45Al5BMG, and their influences on the glass-forming ability and thermal stability were studied in this paper. All the samples remained in full metallic glass state with minor additions of Y, Sm and La. Increasing the amount of RE additions, the Cu10Zr7and Zr2Cu phases precipitated and glass transition temperatureTgand crystallization temperatureTxsignificantly decreased. The reduced glass transition temperature Trg=Tg/Tlranged from 0.592 to 0.611 and the γ parameter ranged from 0.393 to 0.409.

Abstract:

The glassy alloy rods of Cu50Zr43Al7, (Cu50Zr43Al7)100-xYx(x=2,5) and (Cu50Zr43Al7)100-xAgx(x=6,7) with diameters of 3.0 mm were prepared by copper mold suction casting method. The influence of adding Ag and Y to Cu50Zr43Al7 metallic glass on glass formation ability (GFA) and thermal stability was studied by means of X-ray diffraction analysis (XRD) and differential scanning calorimetry (DSC). The results show that Ag and Y appropriate micro-addition enhance the glass formation ability and thermal stability of the Cu-Zr-Al metallic glass. The effect of Ag is better than that of Y. The addition of Ag causes a increase of the reduced glass transition temperature (Trg) of (Cu50Zr43Al7)100-xAgx alloy from 0.618 at 0 at.% Ag to 0.628 at 7 at.% Ag. The width of the supercooled liquid region of Cu43Zr43Al7Ag7 glassy alloy increases about 25K compared with that of Cu50Zr43Al7, and the γ value of Cu43Zr43Al7Ag7 reaches 0.433. The electrochemical corrosion behaviors of Cu50Zr43Al7, (Cu50Zr43Al7)100-xYx(x=2,5) and (Cu50Zr43Al7)100-xAgx(x=6,7) metallic glasses in 3.5% NaCl solution were investigated by potentiodynamic polarization method. It is found that corrosion resistance of all amorphous alloys is better than that of the corresponding crystalline alloys. The Ag and Y micro-addition improve corrosion resistance of Cu50Zr43Al7 metallic glass. The corrosion current density of Cu43Zr43Al7Ag7 metallic glass decreases 1~2 orders of magnitude compared with that of Cu50Zr43Al7.

Abstract:

A series of glasses based on (80-y) TeO2-20 BiCl3-y RE2O3 (y = 0, 0.6 mol%; RE = Nd, Sm, Dy, and Er) were prepared. The thermal stability of the glass was determined by differential scanning calorimetry (DSC). The density and optical energy values of the prepared glass increased in the order of Sm2O3, Nd2O3, Dy2O3, and Er2O3. In addition, the glass doped with Er2O3 had the highest refractive index values compared to the other samples. Subsequently, Judd–Ofelt parameters (Ω2, Ω4, and Ω6) were obtained for the family of RE3+ trivalent rare-earth ions introduced as dopants in a tellurite glass. These parameters were calculated from the absorption spectra for each RE3+. The structures were studied by Raman spectroscopy deconvolution, which determined that TeO4, TeO3, TeO3+1, BiO6, and BiCl6 units had formed. In addition, the structural changes in the glass are related to the intensity ratio of TeO4/TeO3, depending on the type of rare-earth. For the optics and Judd–Ofelt parameters, the ray spectroscopy results of the prepared glass show that it is a good candidate for nonlinear optics fibers, a solid laser material.

Abstract:

Several new bulk metallic glasses based on Fe–Y–Zr–(Co, Cr, Al)–Mo–B, which have a glass-forming ability superior to the best composition Fe61Zr10Co7Mo5W2B15 reported recently, have been successfully developed. The as-cast bulk amorphous alloys showed a distinctly high thermal stability with glass-transition temperatures above 900 K, supercooled liquid regions above 60 K, and high strength with Vickers hardness values larger than HV 1200. The suppression of the growth of primary phases in the molten liquids and the resultant low liquidus temperatures were found to be responsible for the superior glass-forming ability in these new alloys. It was found that the addition of 2% Y not only facilitated bulk glass formation, but the neutralizing effect of Y with oxygen in the molten liquids also improved the manufacturability of these amorphous alloys.

Abstract:

Glass frit plays an important role in the silver paste for silicon solar cells. In this work, we prepare glass frit doped with different rare-earth elements (Y, La, Sm, Er) and study how the doping element affects the performance of the solar cells. Solar cells with La-doped and Sm-doped glass frits show average conversion efficiencies higher than 17.5%, while solar cells with Y-doped or Er-doped frit show lower efficiencies. By analyzing the Raman spectra of the rare-earth doped glass frits, we find that the average coordination number of Te–O ([Formula: see text]) in the glass can be tuned by the rare-earth dopant. La or Sm doping leads to a moderate value of [Formula: see text], which is believed to achieve a glass formation ability that optimizes the structure of the Ag–Si interface of the cell for the best performance.

Abstract:

Fe–Cr–Mo–(Y,Ln)–C–B bulk metallic glasses (Ln are lanthanides) with maximum diameter thicknesses reaching 12 mm have been obtained by casting. The high glass formability is attained despite a low reduced glass transition temperature of 0.58. The inclusion of Y/Ln is motivated by the idea that elements with large atomic sizes can destabilize the competing crystalline phase, enabling the amorphous phase to be formed. It is found that the role of Y/Ln as a fluxing agent is relatively small in terms of glass formability enhancement. The obtained bulk metallic glasses are non-ferromagnetic and exhibit high elastic moduli of approximately 180–200 GPa and microhardness of approximately 13 GPa.

Abstract:

The production of transparent glass-ceramic materials often faces challenges, such as inhomogeneities, inclusions, uncontrolled crystallization and other defects that make glass ceramics unsuitable for fiber optics, for example. At the same time, the chosen chemical composition is valuable for its unique properties. The present study investigated the effect of different methods of synthesizing glass-ceramic silica-germanium-antimony matrices on their transmittance optimization and luminescence properties where the conventional melt-quenching route is insufficient in terms of the transparency and homogeneity of the material obtained. The effect of heat treatment on the studied properties was also considered. Full Text: PDF References G.A. Khater, E.M. Safwat, J. Kang, Y. Yue, A.G.A.

Abstract:

A new Mg–Cu–Ni–Ag–Zn–Y–Gd alloy with significantly improved glass forming ability (GFA) was developed in this work. Mg65Cu7.5Ni7.5Ag5Zn5Y5Gd5 bulk metallic glass (BMG) with a diameter of 14 mm was successfully fabricated by conventional copper mold casting method in air atmosphere. The critical cooling rate for glass formation was estimated to be about 20 K/s. When the maximum diameter for glass formation was compared with those previously reported for Mg-based alloys, the Mg65Cu7.5Ni7.5Ag5Zn5Y5Gd5 alloy showed the highest GFA. However, when the GFA was compared with those of Mg-TM-RE alloys (TM: Cu, Ni, Zn, and Ag; RE: Y and Gd), the significant improved GFA of the Mg–Cu–Ni–Zn–Ag–Y–Gd alloy cannot be properly represented by ΔTx, Trg, K, and γ parameters. In contrast to most of the Mg-based BMGs reported so far, the Mg65Cu7.5Ni7.5Ag5Zn5Y5Gd5 BMG exhibits yielding and plastic deformation during compressive loading.

Abstract:

New ternary zinc oxyfluorotellurite (ZOFT) with the composition(ZnO)x-(AlF3)y-(TeO2)z, where5≤x<35;5≤y≤25;60≤z≤70, has been successfully prepared by the conventional rapid melt quenching technique. Density, molar volume, and glass transition temperature have been assessed for each ZOFT glass sample. The longitudinal and transverse ultrasonic waves propagated in each glass sample were measured using a MBS8020 ultrasonic data acquisition system at 5 MHz frequency and room temperature. The longitudinal modulus (L), shear modulus (G), Young’s modulus (E), bulk modulus (K), and Poisson’s ratio (σ) are assessed from both velocity data and their respective density. The compositional dependence of the ultrasonic velocities and related parameters are discussed to understand the rigidity and compactness of the glass system studied.

This study selected high alkali aluminosilicate glass as the research object. It’s belongs to the SiO2-Al2O3-RO-R2O glass system. By changing the content of Al2O3in the SiO2-Al2O3-RO-R2O glass system, designed five basic glass formula. Using conventional melting method prepared the high alkali aluminosilicate glass. In the case of the same heat treatment, the glass formulations are the most important factor in the glass surface tension. Using the glass surface tension measuring instrument, focus on the content of Al2O3on the glass surface tension’s effects law. The results show that the high alkali aluminosilicate glass’s surface tension are increase with the increase of Al2O3content. The relation between glass surface tension and the content of Al2O3conforms to the formula Y=290+6.5WAl2O3, Al2O3factors influence the surface tension of the glass is 6.5.

Abstract:

Ion irradiation effects on the glass network and structural units have been studied by irradiating borosilicate glass thin film samples with 50 MeV Li3+and 180 MeV Ag14+swift heavy ions (SHI) at different fluence rates ranging from 1012 ions/cm2to 1014 ions/cm2. Glass of the composition (65-x) Bi2O3-10Al2O3-(65-y) B2O3-25SiO2(x= 45, 40;y= 20, 25) has been prepared by melt quench technique. To study the effects of ionizing radiation, the glass thin films have been prepared from these glasses and characterized using XRD, FTIR, and UV-Vis spectroscopic techniques. IR spectra are used to study the structural arrangements in the glass before and after irradiation. The values of optical band gap, Urbach energy, and refractive index have been calculated from the UV-Vis measurements. The variation in optical parameters with increasing Bi2O3content has been analyzed and discussed in terms of changes occurring in the glass network. A comparative study of the influence of Li3+ion beam on structural and optical properties of the either glass system with Ag14+ion is done. The results have been explained in the light of the interaction that SHI undergo on entering the material.

Abstract:

The Thin Blue Line es una de las obras fundamentales de la filmografía de Errol Morris. En este documental se consigue desvelar la inocencia de Randall Adams, acusado por el asesinato de un agente de policía en 1976. Sin embargo, los estudios sobre este film no se han detenido en la consideración de la música compuesta por Philip Glass: ésta juega un papel determinante en la construcción de la inocencia de Adams, así como en el descubrimiento de la corrupción de la justicia estadounidense. De este modo, los reenactments utilizados ampliamente por el director a lo largo del documental dialogarían continuamente con la música de Glass, construyendo entre ambos –tanto en clave irónica, como a través de la repetición– dicha inocencia.

Abstract:

As an important lightweight and high-strength structural material, aluminum alloy is the optimum material for airplane and aircraft. Amorphous Al-based alloys are attractive materials for structural applications because of their high strength of about 1000MPa. Crystallization behavior of amorphous Al-based alloys is critical to the synthesis of high-strength nanocrystalline aluminum alloys in bulk form. The crystallization behavior of an Al85Y8Ni5Co2 metallic glass produced by rapid solidification of the melt was studied in this paper. Microstructure transformation during crystallization was identified by X-ray diffraction. It is found that the initial crystallization of the amorphous alloy occurs through the precipitation of α-Al particles, followed by precipitation of hcp-Al3Y and an unidentified phase.

Abstract:

El presente artículo analiza el desarrollo de la industria vidriera valenciana entre los siglos XIII y XV. Para ello se recurre a un centenar de documentos de carácter notarial, normativo, judicial y fiscal, procedentes de distintos archivos valencianos. Estos permiten estudiar la localización de los hornos de vidrio en el reino de Valencia y las formas de trabajo de los vidrieros, así como los procesos de distribución y los sistemas de venta del vidrio doméstico. Finalmente, se aborda la demanda y el consumo de estos bienes y sus usos en las viviendas de diferentes sectores sociales de la época. Todo ello invita a reconsiderar la relevancia de esta industria en el reino de Valencia, mucho menos estudiada que sus homólogas catalanas y mallorquinas, en el contexto de la Corona de Aragón y del Mediterráneo noroccidental durante la Baja Edad Media. This essay analyses the development of the Valencian glass industry between the 13th and the 15th centuries. For this purpose, it turns to around a hundred documents from notarial, normative, legal and tax records, placed in various Valencian archives. These reveal the location of glass furnaces in the kingdom of Valencia and the glass-makers’ activities, as well as the sale and distribution systems of domestic glass. Finally, it addresses the demand and consumption of these goods and their usage within the dwellings of various social strata of the period. This all leads to reconsider the relevance of this industry in the kingdom of Valencia, far less studied than its counterparts from Catalonia and Majorca, in the context of the Crown of Aragon and the north-western Mediterranean during the later middle ages.

Abstract:

The preparation of Mg49Y15Cu36 metallic glass composite powders was accomplished by mechanical alloying of pure Mg, Y, Cu, and WC powder mixture after 10 h milling. In the ball-milled composites, initial WC particles were homogeneously dispersed in the Mg-based alloy glassy matrix. The metallic glass composites powders were found to exhibit a large supercooled liquid region before crystallization. Bulk metallic glass composites were formed by vacuum hot pressing the as-milled WC/ Mg49Y15Cu36 metallic glass composite powders at 473 K in the pressure range of 0.72-1.20 GPa. BMG composite with submicron WC particles homogeneously embedded in a highly dense nanocrystalline/amorphous matrix was successfully prepared under pressure of 1.20 GPa. It was found that the applied pressure during consolidation could enhance the thermal stability and promotes nanocrystallization of WC/ Mg49Y15Cu36 BMG composites.

Abstract:

(Tl2O3)30-(Li2O)10-(B2O3)(60−y)-(Sm2O3)y glass system with various Sm2O3 additives (y = 0, 0.2, 0.4, 0.6) was studied in detail. The vibrational modes of the (Tl2O3)30-(Li2O)10-(B2O3)(60−y) network were active at three composition-related IR spectral peaks that differed from those mixed with Samarium (III) oxide at high wavenumber ranges. These glass samples show that their permeability increased with the Samarium (III) oxide content increase. Additionally, the electronic transition between localized states was observed in the samples. The MAC, HVL, and Zeff values for radiation shielding parameters were calculated in the energy range of 0.015–15 MeV using the FLUKA algorithm. In addition, EBF, EABF, and ΣR values were also determined for the prepared glasses. These values indicated that the parameters for shielding (MAC, HVL, Zeff, EBF, EABF, and ΣR) are dependent upon the Samarium (III) oxide content. Furthermore, the addition of Samarium (III) oxide to the examined glass samples greatly reinforced their shielding capacity against gamma photon. The findings of the current study were compared to analyses of the XCOM software, some concretes, and lead. In the experiment, it was found that the SMG0.6 glass sample was the strongest shield.

Abstract:

In this research, by dipping technique, a new glass-ceramic coating on a substrate is applied and developed without prior surface chemical treatment as a single coat. For the low-carbon steel with 0.2% C, various glass frit mixture substrates have been selected at different dispersions and are utilized to acquire a glass-ceramics coating that contains the optimum coating features. The test results also indicated that the mechanical properties (hardness, wear rate) of the resultant coating have been greatly improved by both silicate dispersion supplements into the mixture frit for all cases. On this basis, it is found that the wear rate is less than 3.7134 × 10⁻⁷ g/cm that of the specimens coated with glass-ceramic coating (1.175 ×10⁻⁷ g/cm) and that of the base metal, and the hardness value of the glass-ceramic coating (560 HV) is enhanced greatly to reach (760 HV) at silicate dispersion in 700 °C for 120 min. The electrochemical corrosion test in 3.5% NaCl solution showed higher corrosion resistance for the specimen coated with a glass-ceramic (frit) mixture with zirconium 3.777 × 10 mm/y compared to the uncoated specimen 5.533 × 10 -3 mm/y; the specimen coated with a glass-ceramic (frit) mixture with zirconia by dip coating is the best among all specimens.

Abstract:

Based on the analysis of glass formation region of Y2O3-Al2O3-SiO2 glass system, the glass composition 5Li2O-18Y2O3-29Al2O3-48SiO2 (LYAS) in mol% central in the glass formation region of Y-Al-Si glass system was chosen for present work. The Tm3+ and Yb3+ were introduced as activators in LYAS glass. The glass samples were prepared by the high-temperature solid-state melting and then the derived YAG glass-ceramic was obtained by heat-treating the precursor glass. The X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis results indicate that the lattice constant of the obtained glass-ceramic is consistent with the pure YAG phase. The primary crystallite size is calculated to be 46nm and the crystal grains grow with excellent orientation (444) in the internal network. The secondary particle size is estimated to be ~8μm and the large grain size is owing to the particles aggregation. The crystal grains distributed uniformly in the glass matrix, and consistent well with the XRD analysis results.

Abstract:

Although the economic value of glass products and its importance to the Saudi National Economy is vast, not much information is available about the current state of the art of the industry. Likewise little information is available about the geography, potential sites for mining sand as well as the evaluation of sand quality. This paper attempts to bridge this gap by presenting a feasibility study of fabricating normal glass and glass ceramics from Saudi Arabia’s domestically available raw materials. It discusses the current status of glass industry in Saudi Arabia and the Middle East region. It also gives a brief explanation about the sand topography in Saudi Arabia. In order to determine the feasibility of fabricating glass using these raw materials, experimental data on the fabrication of normal glass and glass-ceramics from indigenously available raw materials was obtained and reported as part of the findings of this paper Firstly, normal transparent glass were able to be fabricated without any apparent large defects using sand collected from Ar-Rayis region in Saudi Arabia. Four nano-sized crystallization catalysts, namely VC, WC, TiC and Y2O3, were added to the constituents of the glass in 3 wt.%. For VC, the crystallization process was limited. The glass ceramics of WC consisted of multi-dimensional edges crystals which covered all the matrix. Gray crystalline whiskers were obtained by addition of TiC. The Y2O3- glass ceramics consisted of multi-directionally rosette crystals. Finally, the microhardness values of the added crystallization catalysts glass ceramics were obtained and found to be much higher compared to normal glass. The results show that glass of high quality can be produced specifically for Ar—Rayis region which would be of interest to researchers, glass industry personnel and potential investors

Abstract:

The glass composition (70-x)PbO–(30-y)B2O3–(x+y)AlF3, where x and y ranges from 0 to 20 mol%, were prepared using the conventional melt-quenching-annealing technique. The structural and thermal properties of the glasses were comprehensively analyzed using techniques like Differential Thermal Analysis (DTA), Dilatometry, Fourier-Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), and Scanning Electron Microscopy (SEM). XRD confirmed the amorphous, non-crystalline structure of the glasses. The glass network was found to be composed of structural units such as PbO4, BO4, BO3 and AlO6 using FTIR spectroscopy. FTIR analysis revealed significant structural changes, including the transformation of BO4 to BO3 units and the increase in non-bridging bonds, particularly with higher AlF3 content. DTA was instrumental in determining characteristic temperatures, such as the glass transition, melting, and peak crystallization temperatures, along with glass stability parameters (∆T, Hr, Tgr) for all samples. The study found that the addition of AlF3 led to a decrease in these characteristic temperatures when replacing B2O3, but an increase when replacing PbO. Variations in the density and thermal expansion of the lead borate glass were observed upon the addition of AlF3, decreasing when substituting for PbO and increasing when substituting for B2O3. These findings provide insights into the properties of oxyfluoride glasses, paving the way for future optimization in their composition for varied applications.

Abstract:

The poor thermoplastic formability of reactive Zr-based bulk metallic glass becomes the main limiting factor for replacing the noble-metal-based and Be-rich bulk metallic glasses in nanostructure fabrication. In our work, a (Zr50.7Cu28Ni9Al12.3)98.5Y1.5 bulk metallic glass with good thermoplastic formability has been developed by alloying, where Y addition enlarges the processing window and decreases the viscous resistance of supercooled liquid caused by the high free volume density. The prepared Zr-Cu-Ni-Al-Y bulk metallic glass nanostructure retains the amorphous characteristic and generates the complex oxidization products in the surface layer. The enhanced hydrophilicity of the as-embossed surface follows a Wenzel-impregnating wetting regime, and it can be attributed to the large roughness coefficient induced by the capillary effect. This study provides a low-cost and environmentally friendly bulk metallic glass system to manufacture the nanostructure with a broad prospect in the field of electrocatalysis.

The structure, the thermal and the magnetic properties were studied by X-ray diffraction, differential scanning calorimetry and vibrating sample magnetometry, respectively. Minor Cu addition completely changes the crystallization behavior, and also the glass-forming ability decreases because of the decrease in the supercooled liquid region. However, the magnetic properties are significantly improved upon annealing because of the precipitation of (Fe,Co) phase. In case of [(Fe0.5Co0.5)0.75B0.2Si0.05]96Nb4}100-x (Gdx) glass, Gd addition does not change the crystallization behavior. In turn, it increases the supercooled liquid region when compared with [(Fe0.5Co0.5)0.75B0.2Si0.05]96Nb4, but even then the glass-forming ability is reduced (critical glassy diameter dc < 1.5 mm). The saturation magnetization of the glass is also decreased with increasing Gd content.

The gamma ray interaction parameters, μ/ρ, HVL, TVL, ZPIeff, and Ne,eff, were computed for photon energy range 1 keV–100 GeV. The macroscopic fast neutron removal cross-sections (ΣR) have also been calculated. Appreciable variations were noted for all the interaction parameters by varying the photon energy and the chemical composition of the glass samples. The better shielding properties of borate glass samples containing PbO were found. These results indicated that borate glass samples are a good radiation shielding material.

Abstract:

Silicon nitride ceramic composites were bonded using mixed Y2O3, La2O3, Al2O3, and SiO2 powers. The effect of bonding conditions on the joint strength was studied. The joint strength under different bonding conditions was measured by four-point bending tests. The interfacial microstructures were observed and analyzed by scanning electron microscopy, electron probe microanalysis (EPMA), and x-ray diffraction (XRD), respectively. The results of EPMA and XRD analyses showed that the liquid/glass solders reacted with silicon nitride at the interface, forming a Si3N4//Si2N2O/Y–La–Si–Al–O–N glass/Y–La–Si–Al–O glass gradient interface. From the results of the four-point bending tests, it is known that with an increase in bonding temperature and hold time, the joint strength first increased, reached a peak, and then decreased. LaYO3 precipitated from the joint glass can improve strength of the joint at both room and high temperatures.
