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.
