Contact with graphite may cause the formation of tantalum carbide and lead to the embrittlement of the tantalum. Although tantalum can usually be combined without problems with other refractory metals such as molybdenum or tungsten, it may react with hexagonal boron nitride and silicon nitride.
Tantalum carbide is widely used as sintering additive in ultra-high temperature ceramics (UHTCs) or as a ceramic reinforcement in high-entropy alloys (HEAs) due to its excellent physical properties in melting point, hardness, elastic modulus, thermal conductivity, thermal shock resistance, and chemical stability, which makes it a desirable ...
Description. Tantalum carbide (TaC) is an extremely hard (Mohs hardess 9-10) refractory ceramic material. The hardness is only exceeded by diamond. It is a heavy, brown powder usually processed by sintering, and an important cermet material. It is sometimes used as a fine-crystalline additive to tungsten carbide …

Tantalum Carbide also acts as a grain growth inhibitors preventing the formation of large grains, thus producing a materials of optimal hardness. It is also used as a coating for steel moulds in the injection moulding of aluminium alloys. While providing a hard, wear resistant surface, it also provides a low friction mould surface.
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, & …
Considering the efficient production of methyl radicals from the methyl-substituted silacyclobutane molecules, we explore, in this present work, the growth of tantalum carbide and tungsten carbide films using the method of HWCVD with a new methyl-substituted silacyclobutane precursor, i.e., 1-methylsilacyclobutane (MSCB).
