Tantalum Carbide Powder

Tantalum carbide powder is an extremely hard refractory ceramic material. The hardness of tantalum carbide is only exceeded by diamond. It (TaC powder, Ta2C powder) is a heavy, brown powder usually processed by sintering, and an important cermet material. Tantalum carbide powder 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).

Synonyms: Tantalum carbide, TaC, Ta2C, tantalum carbide powder, tantalum carbide TaC, tantalum carbide Ta2C
Purity:  99.0% to 99.5%
Products: Tantalum carbide targets, tablets, pieces, and powder (100-325 mesh)

Typical Applications for tantalum carbide powder

-Added to tungsten carbide/cobalt (WC/Co) powder attrition to enhance the physical properties of the sintered structure.
-Used as a coating for steel molds in the injection molding of aluminum alloys. While providing a hard, wear resistant surface, tantalum carbide powder also provides a low friction surface.
-Used in the production of sharp instruments with extreme mechanical resistance and hardness.
-Also used in tool bits for cutting tools.
