Silica can also be used to make silicon carbide by heating high-purity silica sand with petroleum coke to temperatures between 2,200° C and 2,400° C for 36 hours. The silicon carbide is then crushed and ground to the desired size. Silicon carbide is used as an abrasive, as a refractory, as moulds and as a component of metal-matrix composites.
