Vanadium carbide is a chemical compound selected from the group of carbides.

Occurrence

Vanadium carbide is formed in vanadium-containing (steel ) alloys. There is, in addition to tungsten carbide ( WC), one of the (thermal) dar. special stable carbides

Production and representation

Vanadium carbide can be obtained by the reaction of vanadium pentoxide or vanadium with carbon.

Properties

Vanadium carbide has a cubic, the sodium chloride -like crystal structure. This also existing Vanadiumdicarbid VC2 (CAS :12542 -39 -1, melting point 2165 ° C ), however, has a pseudo-hexagonal crystal structure.

Use

Vanadium carbide is due to its high hardness and temperature resistance commercially for tool bits and cutting tools, as well as in alloys ( inhibits grain growth ), used for surface coatings and cermets eg together with tungsten carbide.

Safety

Vanadium carbide is classified as carcinogens and mutagens each classified in category 2.
