Silicon carbide — Wikipedia Republished // WIKI 2

Because natural moissanite is extremely scarce, most silicon carbide is synthetic. Silicon carbide is used as an abrasive, as well as a semiconductor and diamond simulant of gem quality. The simplest process to manufacture silicon carbide is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 C (2,910 F) and 2,500 C (4,530 F).


Silicon Carbide is a ceramic material with numerous appliions in the manufacturing, automotive, defense, electronics, lighting, and steel industries. Ultra high purity, high purity, submicron and nanopowder forms may be considered.
