pure reaction of silicon carbide to form silica

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

Silicon | Tradeasia International

Silicon of 96–99% purity is made by reducing quartzite or sand with highly pure coke. The reduction is carried out in an electric arc furnace, with an excess of SiO 2 used to stop silicon carbide (SiC) from accumulating. SiO 2 + 2C → Si + 2CO. 2SiC + SiO 2 → 3Si + 2CO
