Tantalum Carbide Powder Tantalum carbide (TaC) is an extremely hard (Mohs hardess 9-10) refractory ceramic material. The hardness is only exceeded by diamond. It is a heavy, brown powder usually processed by sintering, and an important cermet material.

Zirconium Carbide powder It has the appearance of a gray metallic powder with cubic crystal structure. It is highly corrosion resistant. Like most carbides of refractory metals, zirconium carbide is sub-stoichiometric, i.e., it contains carbon vacancies. At carbon contents higher than approximately ZrC0.98 the material contains free carbon. ZrC is stable for a carbon-to-metal ratio […]
