Silicon Carbide

Silicon Carbide or Carborundum is a widely used abrasive.  Silicon Carbide has the formula SiC.  It occurs naturally as moissanite, though it is quite rare.  Most Silicon Carbide is synthetically made.    It is very hard, which makes it useful in cutting tools.

Silicon Carbide is also used in hard ceramics.  These ceramics are formed by sintering grains of Silicon Carbide.  Such ceramics are used as in car brakes and in clutches.

In Electronics, Silicon Carbide is used as semiconductors and in LEDs (Light Emitting Diodes). Silicon Carbide is used in the making of  bullet proof vests. It is also used as a refractory material in furnaces as it can with stand high temperatures.
