Tantalum Carbide (TaC)-Powder

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.

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.
