Tantalum Carbide Powder

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

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.[5] ZrC is stable for a carbon-to-metal ratio […]

Chromium Powder

Chromium Powder  is the hardest metal element in the periodic table and the only element that exhibits antiferromagnetic ordering at room temperature, above which it transforms  into a paramagnetic solid. Chromium does not oxidize in air, even in extreme moisture.
