Tantalum Carbide Powder Introduction
Tantalum carbide is a brown, hard refractory ceramic material. The TaC powder is hard, brittle, and exhibits high thermal and electrical conductivity. It is processed through sintering and enhances oxidation resistance, hot hardness, and temperature strength in steel processing. Our tantalum carbide powder is supplied in minimal grain sizes and is often used in deposition and evaporation processes and in applications where high surface areas are desired.
TaC can be used to improve hard metal cutting tools which are quite important due to their uses in growth markets such as the automobile and aerospace. Tantalum niobium carbides make big contributions toward improvements in oxidation resistance, hot-hardness, and high-temperature strength besides resistance to crater wear during the processing of steels. Thanks to their thermal conductivity, they also increase resistance to thermal cracking, which can occur due to thermal shock effects during milling, for example.
