Carborundum

Car`bo*run"dum\, [Carbon + corundum.] A beautiful crystalline compound, SiC, consisting of carbon and silicon in combination; carbon silicide. It is made by heating carbon and sand together in an electric furnace. The commercial article is dark-colored and iridescent. It is harder than emery, and is used as an abrasive.

Carborundum

exceedingly hard, synthetically produced crystalline compound of silicon and carbon. Its chemical formula is SiC. Since the late 19th century silicon carbide has been an important material for sandpapers, grinding wheels, and cutting tools. More recently, it has found application in refractory linings and heating elements for industrial furnaces, in wear-resistant parts for pumps and rocket engines, and in semiconducting substrates for light-emitting diodes.
