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).

In all polytypcs except 3C- and riH-Sif atomic hiyers wilh cubic (C) and hexagonal (H) symmetry follow in a regular alternation in the direct ion of the c axis. This can be thought of as anutural one-dimensional superkmice imposed on the "pure" i.e. h-layer free 3C-SiC [ Dean et al. (1977) ], the period of the superlattice being different for different modifiions.
