Introduction
Silicon Carbide Castable are made from high-grade silicon carbide and industrial silicon powder as raw materials. Which is one of the unshaped refractory materials. It is made of refractory aggregate, refractory powder, binders and other additives. It is one of the new type refractory material of don’t need calcination.
