Tantalum carbide Nanopowder (TaC) Properties and Applications:
Tantalum carbide (TaC) is an extremely hard (Mohs hardess 9-10) refractory ceramic material, commercially used in tool bits for cutting tools. The hardness is exceeded by diamond. It is a heavy, brown powder usually processed by sintering, and an important cermet material. It is sometimes used as a fine-crystalline additive to tungsten carbide alloys. Tantalum carbide has the distinction of being the stoichiometric binary compound with the highest known melting point, at 4150 K (3880°C) and boiling point, at 5500 oC. The substoichiometric compound TaC0.89 has a higher melting point, near 4270 K (4000°C).
