Silicon Carbide Silicon Carbide (SiC) is produced in an electric
furnace at temperatures in excess of 2200ºC. SiC is produced by
fusing coke and high purity silica sand. The result is the
formation of SiC crystals which are very hard. SiC also has a very
high thermal conductivity and is very strong at elevated
temperatures. SiC is used in a variety of industries including
Bonded Abrasives (grinding wheels), Coated Abrasives (sandpaper and
cloth), wire sawing granite, blasting grain, polishing compounds,
refractories, structural ceramics, heating elements, and other
applications.
