Silicon carbide (SiC) is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite.
Grains of silicon carbide can be bonded together by sintering to form very hardceramics that are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests. Electronic applications of silicon carbide as light-emitting diodes (LEDs) etc.
