Increasing Si and C During Melting Using Graphite …
It is commercially produced by the reduction of silica sand with carbon, in the form of petroleum coke, in cylindrical electric resistance furnaces. The outer layer of the furnace product, containing approximately 90% SiC is known as foundry melting silicon carbide and can be used as an alloying additive for introducing silicon and carbon into gray cast iron, ductile iron and steel melts.
