Tantalum carbide Nanopowder (TaC) Properties and Applications:
1. Tantalum carbide (TaC) is an extremely hard (Mohs hardess 9-10) refractory ceramic material, commercially used in tool bits for cutting tools.
2. 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.
3. The substoichiometric compound TaC0.89 has a higher melting point, near 4270 K (4000°C).
4. 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.
