USE OF SILICON CARBIDE IN THE INDUCTION FURNACE

The silicon carbide is obtained by electromelting high purity silica sand with petroleum coke, also of good quality. This “melting” takes place at high temperature (about 4000 OF (2200 OC)) and requires a large quantity of energy to produce. It also requires energy for it to dissociate into about 2/3 Si and 1/3 C in the induction furnace.
