Characteristic
Tantalum carbides form a family of binary chemical compounds of tantalum and carbon with the empirical formula TaCx, where x usually varies between 0.4 and 1. They are extremely hard, brittle, refractory ceramic materials with metallic electrical conductivity. They appear as brown-gray powders, which are usually processed by sintering.
Chemical formula：TaC
Molar mass：192.96 g/mol
Appearance：Brown-gray powder
Odor： Odorless
Density：14.3–14.65 g/cm3 (TaC)；15.1 g/cm3 (TaC0.5)
Melting point：3,850–3,880 °C (6,960–7,020 °F; 4,120–4,150 K)
(TaC)；3,327 °C (6,021 °F; 3,600 K)(TaC0.5)
Boiling point：4,780–5,470 °C (8,640–9,880 °F; 5,050–5,740 K)(TaC)
Solubility in water：Insoluble
Application
Tantalum carbides is used in tungsten carbide. It is also used as a coating for steel moulds in the injection moulding of aluminum alloys. While providing a hard, wear resistant surface, it also provides a low friction mould surface. It is also used in the production of sharp instruments with extreme mechanical resistance and hardness, tool bits for cutting tools.
