Silicon Carbide Production Process | Saint-Gobain Silicon CarbideSilicon Carbide (SiC) is a synthetic mineral most commonly produced in electrical resistance furnaces, by the Acheson process, named after the American E.G. Acheson who invented it in 1891. In an Acheson furnace, a mixture of carbon material (usually petroleum coke) and a silica or quartz sand is reacted chemically at.silicon carbide powder manufacturing process,Silicon carbide - WikipediaBecause 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 combine silica sand and carbon in an Acheson graphite.
