For example, porous tantalum coatings are used in the construction of titanium implants due to tantalum's exceptional ability to form a direct bond to hard tissue. [74] Because tantalum is a non-ferrous, non-magnetic metal, tantalum implants are considered to be acceptable for patients undergoing MRI procedures.
The first tantalum electrolytic capacitors with wound tantalum foils and non-solid electrolyte were developed in 1930 by Tansitor Electronic Inc. (US), and were used for military purposes. [ 21 ] Solid electrolyte tantalum capacitors were invented by Bell Laboratories in the early 1950s as a miniaturized and more reliable low-voltage support ...
Tantalum carbide is widely used as sintering additive in ultra-high temperature ceramics (UHTCs) or as a ceramic reinforcement in high-entropy alloys (HEAs) due to its excellent physical properties in melting point, hardness, elastic modulus, thermal conductivity, thermal shock resistance, and chemical stability, which makes it a desirable ...
Aluminum, tantalum and niobium electrolytic capacitors are named after the material used as the anode and the construction of the cathode (electrolyte) Polymer capacitors are aluminum, tantalum or niobium electrolytic capacitors with conductive polymer as electrolyte
The EPVD process generates thick coatings (50 to 300 microns) needed for gun barrels and can be adapted for small, medium, and large calibers. It applies engineered multilayer coatings using mostly metallic or ceramic materials, predominantly featuring tantalum, tungsten, and other refractory metals. [citation needed]
Tantalum arsenide is a compound of tantalum and arsenic with the formula TaAs. It is notable as being the first topological Weyl semimetal that was identified and characterized by ARPES . [ 3 ]
With the addition of squarate or perchlorate, the tantalum complex dimerises in acetonitrile, with their respective chelating ligands bridging the Ta centres. These seven-coordinate complexes of the form TaMe 3 L 2 , where L is a bidentate monoanion, are markedly more thermally stable than their precursor, decomposing in the range 80 - 120°C.
Tantalcarbide is a rare mineral of tantalum carbide with formula TaC. With a molecular weight of 192.96 g/mol, its primary constituents are tantalum (93.78%) and carbon (6.22%), and has an isometric crystal system. [2] It generally exhibits a bronze or brown to yellow color. On the Mohs hardness scale it registers as a 6–7. [3]
