silicon carbide is made of petroleum coke and silica as the main raw materials, adding salt as additives, and smelting at high temperature in a resistance furnace.

Silicon carbide is an ideal compound deoxidizer, desulfurizer.ca and si has a strong affinity with oxygen. Especially calcium, not only has a strong affinity with oxygen , and sulfur, nitrogen has a very strong affinity.

Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials.

Silicon carbide includes black silicon carbide and green silicon carbide, among which: black silicon carbide is made of quartz sand, petroleum coke and high-quality silica as the main raw materials, which are smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, its mechanical strength is higher than corundum, and it is brittle and sharp. Green silicon carbide is made from petroleum coke and high-quality silica as the main raw material, adding salt as an additive, and smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, and its mechanical strength is higher than that of corundum.

silicon carbide is produced at high temperature in an electric resistance type furnace with quarts 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 sharp and has electrical and heat conductivity in some degree.

Silicon carbide(silicon carbide block), also known as emery or refractory sand, has a chemical formula of SiC and is a very widely used inorganic substance. There are two types of silicon carbide obtained by industrial production, namely black silicon carbide and green silicon carbide.
