Silicon Carbide Formula - Silicon Carbide …

Occurrence: Silicon carbide occurs naturally as the rare mineral moissanite. Preparation: Silicon carbide is prepared industrially by the Acheson method, in which pure silica sand (SiO 2) and finely ground coke (carbon) are mixed together and heated to very high temperatures in an electric furnace. SiO 2 + 3 C → SiC + 2 CO
