Tantalum carbide (TaC) is a binary compound of tantalum and carbon with the chemical formula TaC x, where x usually varies between 0.4 and 1. They are extremely hard, brittle, refractory ceramic materials with metallic conductivity. They are brown-grey powders and are usually processed by sintering.
Tantalum carbide is an important metal ceramic material. One very important use of tantalum carbide is tantalum carbide coating.
Product characteristics of tantalum carbide coating
High melting point: The melting point of tantalum carbide is as high as 3880°C, which makes it stable in high temperature environments and not easy to melt or degrade.
Working condition : In general, the normal Working condition of Tantalum carbide (TaC) is 2200°C. Considering its extremely high melting point, TaC is designed to withstand such high temperatures without losing its structural integrity.
Hardness and wear resistance: It has extremely high hardness (Mohs hardness is about 9-10) and can effectively resist wear and scratches.
Chemical stability: It has good chemical stability to most acids and alkalis and can resist corrosion and chemical reactions.
Thermal conductivity: Good thermal conductivity enables it to effectively disperse and conduct heat, reducing the impact of heat accumulation on the material.
