Abstract:

Oxides containing aluminium and barium, optionally with chromium, are refractory with several possible industrial uses. A gel precursor of an oxide having the formula BaO.n(Al2xCr2yO3), where 1<n<6.6, (x+y)=1 and 0<y<0.5 was prepared by mixing a solution of a barium salt with a solution of an aluminium salt or a solution of an aluminium salt and a chromium III salt, then forming a gel which was fired to obtain the desired oxide. Filaments may be drawn as the gel is forming or extruded from a semi-rigid gel. FT-lR, XRD and 27Al NMR studies showed that barium is not incorporated dire

Abstract:

Aluminium titanate was synthesized using waste aluminium sludge and chemical pure TiO2 powder as raw materials. Effect of different compositions on crystal structure and contents of target product was discussed. XRD results showed that four crystal phases, aluminium titanate, perovskite, rutile and aluminum oxide, are formed in the sintered samples. The content of aluminium titanate increases first and then decreases with the decrease of the content of waste aluminum sludge. When the content of the sludge is 65.52wt%, the content of aluminium titanate reaches the maximum of 86.1wt%.

Phase composition, structure, conductivity and electrical properties of LYMA have been investigated as a function of aluminium content by X-ray diffraction, scanning electron microscopy and electrochemical impedance spectroscopy, respectively. Experimental results showed tha

Abstract:

The densification behaviour, mechanical properties, and microstructure of high-purity Al2O3 and CeO2-doped Y-TZP with different weight percentage varied from 0.3 to 1 wt% were investigated. The samples were pressed uniaxially at 200 MPa into rectangular bars and discs and pressureless-sintered at temperature ranging between 1250°C and 1450°C for 2 h while the microstructure was characterized with a scanning electron microscope (SEM). Two-step sintering process works well for temperature higher than 1400°C and it created most tetragonal phase arrangement for stable structure to delay ageing thr

Abstract:

The paper presents the study of CdS0.2Se0.8 n-type films 0.50-0.65 µm thick manufactured by the RF sputtering technique and their electro-optical properties. The effects of the substrate texturing on the structure and properties of the films are discussed. Recrystallization of the films sputtered onto glass substrates coated with a continuous or island-like silver sublayer resulted in the formation of a nanosized grain structure with higher photosensivity than films deposited onto aluminium oxide ceramics.
