Black Silicon Carbide for Sandblasting and Refractory

Black Silicon Carbide for Sandblasting and Refractory

Product Description

Black silicon carbide is produced at high temperature in an electric resistance type furnace with quartz sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is brittle and sharp and sharp and heat conductivity in some degree. The abrasive made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc It is also broadly used as refractory material and metallurgical additive.

Main Features

Silicon Carbide Castable can greatly reduce the number of skinning, with fast thermal conductivity, compact volume, good oxidation resistance, good wear resistance, anti erosion, anti permeability and other advantages.
