Tantalum carbide hardness, high melting point, high temperature performance, mainly used as a cemented carbide additive. The thermal hardness, thermal shock resistance and thermal oxidation resistance of cemented carbide can be significantly improved by increasing the grain size of tantalum carbide. For a long time, a single tantalum carbide is added to tungsten carbide (or tungsten carbide and titanium carbide), and the binder metal cobalt is mixed, formed, and sintered to produce cemented carbide. In order to reduce the cost of cemented carbide, often use tantalum niobium complex carbide, now the main use of tantalum niobium complex are :TaC:NbC is 80:20 and 60:40 two, niobium carbide in the complex energy reached 40% (generally thought not to exceed 20% is good).
