Description
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.
Characteristic of silicon carbide
High hardness, good thermal conductivity, thermal expansion coefficient is small, stable chemical performance, wear-resisting performance is good, crispy.
Application of silicon carbide
Abrasives, polishing, grinding, sandblasting, fire-proof material, functional ceramics, metallurgy, steel deoxidization, auto parts.
