Abstract:

Tantalum metal was soaked in NaOH and CaCl2 solutions, and then subjected to heat treatment at 500°C. EDX analysis showed that about 6.5 at. % of Na was incorporated into the surface of the tantalum metal by the first NaOH treatment. These Na+ ions were replaced by Ca2+ ions by the subsequent CaCl2 treatment. According to TF-XRD patterns, an amorphous sodium tantalate was seemed to be formed on the tantalum metal by the NaOH treatment and transformed into amorphous calcium tantalate by the CaCl2 treatment. This phase was crystallized into Ca2Ta2O7 by heat treatment. Critical detaching load of the surface of the CaCl2-treated tantalum metal was as low as 5mN, while as high as 42mN after the heat treatment. Apatite-forming ability of the NaOH-treated tantalum metal in a simulated body fluid (SBF) was appreciably increased by the CaCl2 treatment and maintained even after the heat treatment.

Abstract:

Terak Timah merupakan produk samping dari proses peleburan timah yang mengandung unsur logam tantalum dan niobium. Beberapa sumber unsur tantalum dan niobium yaitu columbite, tantalite, tantalo-columbite, dll. Tantalum & niobium memiliki banyak aplikasi seperti industri pesawat terbang, elektronik dan super alloy. Penelitian ini dilakukan untuk meningkatkan kadar unsur logam tantalum dan niobium dari terak timah melalui proses pelindian asam maupun basa. Hasil penelitian menunjukan bahwa proses pemanggangan yang dilakukan tidak mengalami dekomposisi thermal, selanjutnya proses pelindian basa dengan NaOH mengakibatkan penurunan yang sangat kecil terhadap niobium yaitu dari 0,75 menjadi 0,73%, sedangkan proses pelindian dengan HNO3 dan H3PO4 memberikan peningkatan terhadap tantalum dan niobium yaitu dengan HNO3 2M menghasilkan Ta dan Nb berturut-turut 0,17 menjadi 0,85 dan 0,73 menjadi 1,49. Hal ini juga terlihat pada pelindian menggunakan campuran HNO3: H3PO4 menghasilkan peningkatan Ta dan Nb berturut-turut menjadi 0,88-0,9% dan 1,46-1,54% di setiap peningkatan variasi konsentrasi H3PO4

Abstract:

The synthesis of lithium tantalate films by a chemical solution deposition method was studied. A precursor solution was prepared by dissolving lithium ethoxide and tantalum pentaethoxide in ethanol. The addition of formic acid to this precursor solution was very effective in the preparation of homogeneous and transparent precursor films on substrates by spin coating. Lithium tantalate films crystallized on sapphire (001) substrates with a highly preferred orientation along the c axis with heat-treating at temperatures above 450 °C. The refractive index of the film prepared at 550 °C was 2.049, which is close to the value for single crystals of lithium tantalate (2.176).

Abstract:

(Na0.6H0.4)(Ta0.7Nb0.3)O3 was synthesized by heating a tantalum/niobium scale containing two sodium tantalate/niobate phases :Na14(Ta0.7Nb0.3)12O37·31H2O and NaH2Ta0.7Nb0.3O4. Powder X-ray diffraction data for (Na0.6H0.4)(Ta0.7Nb0.3)O3 indicated it to be a cubic perovskite (ABO3/ReO3 type structure) with unit cell a0=3.894 Å. The compound is analogous to the mineral lueshite (NaNbO3), and to the high temperature forms of NaTaO3 and NaNbO3. Powder diffraction data for (Na0.6H0.4)(Ta0.7Nb0.3)O3 will be useful in the analysis of synthetic tantalum/niobium concentrates.

Full text

Abstract:

Cranioplasty is a unique procedure with a rich history. Since ancient times, a diverse array of materials from coconut shells to gold plates has been used for the repair of cranial defects. More recently, World War II greatly increased the demand for cranioplasty procedures and renewed interest in the search for a suitable synthetic material for cranioprostheses. Experimental evidence revealed that tantalum was biologically inert to acid and oxidative stresses. In fact, the observation that tantalum did not absorb acid resulted in the metal being named after Tantalus, the Greek mythological figure who was condemned to a pool of water in the Underworld that would recede when he tried to take a drink. In clinical use, malleability facilitated a single-stage cosmetic repair of cranial defects. Tantalum became the preferred cranioplasty material for more than 1000 procedures performed during World War II. In fact, its use was rapidly adopted in the civilian population. During World War II and the heyday of tantalum cranioplasty, there was a rapid evolution in prosthesis implantation and fixation techniques significantly shaping how cranioplasties are performed today. Several years after the war, acrylic emerged as the cranioplasty material of choice. It had several clear advantages over its metallic counterparts. Titanium, which was less radiopaque and had a more optimal thermal conductivity profile (less thermally conductive), eventually supplanted tantalum as the most common metallic cranioplasty material. While tantalum cranioplasty was popular for only a decade, it represented a significant breakthrough in synthetic cranioplasty. The experiences of wartime neurosurgeons with tantalum cranioplasty played a pivotal role in the evolution of modern cranioplasty techniques and ultimately led to a heightened understanding of the necessary attributes of an ideal synthetic cranioplasty material. Indeed, the history of tantalum cranioplasty serves as a model for innovative thinking and adaptive technology development.

Abstract:

Due to the great potentials of tantalite and niobate materials in ferroelectric and photocatalytic applications, development of proper tantalum or niobium precursors is urgently need. In this work, a simple novel route to synthesize environmentally friendly aqueous tantalum and niobium precursors has been developed using cheap and stable Nb2O5 or Ta2O5 as starting source. Using home-made Ta and Nb precursors, several photocatalytic nanopowders such as BiNbO4 and BiTaO4, and ferroelectric ceramics such as 0.65Pb(Mg1/3Nb2/3)O3-0.35PbTiO3 (PMN-PT), have been prepared by a modified PC method. These powders and ceramics from polymeric precursors have low crystalline temperature and transformation temperature with uniform grain distribution, compared to conventional solid phase reaction (SSR). Pure triclinic phase of BiNbO4 powders can be obtained at 700°C instead of 1020°C of SSR, with excellent photodegradation activity of methyl violet. PC-derived PMN-PT ceramics also exhibit better ferroelectric and piezoelectric properties. All these indicate that this is an attractive and flexible approach using environmentally friendly water-soluble tantalum and niobium precursors for fabrication of tantalate and nibonate functional materials.

Abstract:

Background: Lithium tantalate (LiTaO3) thin film was synthesized and in situ coated on tantalum substrate via anodic oxidation. Methods: The effects of temperature, voltage and time on composition, morphology and hardness of film were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Vickers hardness, respectively. Results: Our results showed that surface hardness of all coated samples has been increased compared with that of pure tantalum. The value of hardness was found to gradually increase with temperature, voltage and reaction time of the coating process. Selected specimens, after coating, were immersed into 10 wt% NaOH solution at 50oC for 96h to explore their anti-corrosion performance. Immersing results indicated that LiTaO3 coated samples have a smaller mass loss and corrosion rate compared to those of pure Ta substrate. Pure tantalum sample and those coated by LiTaO3 thin film were further examined by electrochemical methods including open-circuit potential (OCP), potentiodynamic polarization curves and electrochemical impedance spectra (EIS). Conclusion: We have found that samples coated with LiTaO3 thin film exhibit higher potentials and lower corrosion current densities than those of pure tantalum substrate, according to the results and analysis of OCP curves and potentiodynamic polarization curves. Upon anodic oxidation, samples display higher polarization resistance with higher resistance to corrosion.

Abstract:

A method was developed for synthesis of a single phase lithium tantalate charge doped by rare earth elements (TR) from highly pure solutions containing tantalum. The method is based on obtaining and thermal treatment of citrate precursor containing Li, Ta and TR. Charge samples were obtained due to suggested technological scheme; the dopant had given concentration and was chemically uniformly distributed. The charge can be applied both in single crystal growing technology and at obtaining of functional ceramics based on LiTaO3:TR.
