Black Silicon Carbide | Silicon Carbide Companies - Wilson
Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina.
Production. Due to the rarity of natural moissanite, silicon carbide is typically man-made. Most often it is used as an abrasive where it is often known by the trademark carborundum, and more recently as a semiconductor and diamond simulant of gem quality. The simplest manufacturing process is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high
