    • n Carborundum Silicon carbide, SiC, a product of the electric furnace used as an abrasive material. The reaction of the furnace is SiO2+3C = SiC+2CO. This substance is manufactured in powerful electric furnaces upon a large scale. It is used as a powder of various degrees of fineness and is also consolidated into blocks for grinding-wheels. Carborundum is substituted for ferrosilicon in steel-making and is mixed with a strong solution of water-glass (sodium silicate) to form a paste for application to the lining of a furnace, protecting it from injury by very high temperature. It has been identified in the meteoric iron of Cañon Diablo, Arizona, and named moissanite.
