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
