Black Silicon Carbide for Refractories

Black Silicon Carbide(SiC) is one of the most important refractory materials along with Brown Fused Alumina and White Fused Alumina. It has high hardness, low expansion rate, good chemical stability, good heat conductivity and is widely used in Refractory Bricks, Unshaped Refractories, Special Ceramic Products, Precision Casting, Foundry and Metallurgical Industry. Black Silicon Carbide refractory grades is the most consumed one among Silicon Carbide family.
