Saint-Gobain do Brasil Materiais Cerâmicos produces silicon carbide which, traditionally, is used as raw material in the production of abrasives (grinding wheels, sandpaper, cutting wheel) and refractory (bricks, crucibles, mass for buffering, blast furnace gutters), in addition to be used as input for the steel area.
It started to operate in 1980 in Barbacena/MG and was incorporated into Saint-Gobain in 1999.
Silicon carbide is obtained through the mixture between the silica (sand or quartzite) and carbon (petroleum coke) taken to a resistance furnace. This process is discontinuous due to the product characteristics; melting does not occur, that is, the reactions occur in the solid state.
