Tantalum carbides (TaC) form a family of binary chemical compounds of tantalum and carbon with the empirical formula TaC x, where x usually 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.

Tantalum carbide, TaC, is primarily produced through the reduction-carburization of Ta2 O 5 with carbon at temperatures from 1600 to 2000 °C (Kirk-Othmer, 1978d, pp. 547-560; Miller, 1959; Schwarzkopf & Kieffer, 1953). The general form of the reaction is (Shimada, Koyama, Kodaira, & Matsushita, 1983) as follows.

Tantalum carbide (Ta C) is an extremely hard refractory ceramic material, commercially used in tool bits for cutting tools. It is a heavy, brown powder usually processed by sintering, and an important cermet material. It is sometimes used as a fine …

Transition-metal carbides (TMC) are candidate materials for ultra-high temperature ceramics (UHTC), due to their high melting points (2000–4000 °C), huge modulus and resistance to chemical attack. 1–3 Amongst UHTC materials, tantalum carbide, TaC, is a desirable candidate for next generation thermal heat protection, scramjet components ...
