tantalum carbide properties
Tantalum carbide powder, with 6.224% Carbon and 192.96 molecular weight, is snuff-colored powder, hard and heavy, with high chemical stability and good high-temperature performance. The density is 14.5g/cm3, the melting point is 3875℃, the boiling point is 5500℃. TaC is an important metal-ceramic material. Cutting tools made of TaC can be resistant to the high temperature of 3800℃, and its hardness is comparable to the prestigious diamond. As a grain refiner of tungsten-based hard metal, TaC can promote obviously the performance alloy, and its content reaches 0.5-5% in tungsten-carbide-base cemented carbide.
