Brief Description of TaC Tantalum carbide powder

Tantalum carbides form a family of binary chemical compounds of  tantalum  and carbon  with the empirical formula TaCx, where xusually 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 .

Being important cermet  materials, tantalum carbides are commercially used in tool bitsfor cutting applications and are sometimes added to tungsten carbide alloys.

Properties of TaC Tantalum carbide powder

Tantalum carbides have metallic electrical conductivity, both in terms of its magnitude and temperature dependence.

TaC is a superconductor  with a relatively high transition temperature of TC = 10.35 K.
