What Wikipedia says

Silicon carbide (SiC), also known as carborundum (), is a hard chemical compound of silicon and carbon. A wide bandgap semiconductor, it occurs in nature as the extremely rare mineral moissanite, but has been mass-produced as powder and crystals since 1893 for use as an abrasive.
