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
Being important cermet materials, tantalum carbides are commercially used in tool bits for cutting applications and are sometimes added to tungsten carbide alloys.
