Carbon & Carbide
Silicon Carbide
Silicon carbide combines very high hardness, high thermal conductivity, low thermal expansion and strong resistance to oxidation, slag and thermal shock. It is a key additive and aggregate in refractories for blast furnaces, ladles, kilns and incinerators, and is widely used as an abrasive.
