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).

The process enables graphene to be produced directly onto semiconductor-compatible substrates such as silicon, silicon-carbide, sapphire and gallium-nitride. It does not require alytic formation of the graphene so eliminating metallic contamination and allows synthesis of large areas of the material (up to 8” diameter to date).

Direct growth of graphene on aluminium nitride on silicon

Another technique to grow graphene is to anneal silicon carbide (SiC) substrates at ~1200 C, driving out the silicon from the surface and leaving the carbon atoms in a graphene structure. Recently, techniques have been developed for molecular beam epitaxy (E) and chemical vapor deposition (CVD) of graphene on silicon carbide and sapphire.
