Refractory Grade Silicon Carbide

Black silicon carbide is made of quartz sand, petroleum coke (or coal) and wood chips as raw materials through a resistance furnace with high temperature smelting. Of the non oxide high technology refractory materials such as C, N and B, silicon carbide is the most widely used and most economical kind of refractory material.
