China Manufacture SiC F20 Green Silicon Carbide
Green Silicon Carbide For Surface treatment
Green silicon carbide is characterized by extreme hardness (Mohs 9.4/2600 Knoop) which only rank after CBN and B4C.
Green Silicon Carbide (SiC) is an extremely hard (Mohs 9.4 / 2600 Knoop) man made mineral that possesses high thermal conductivity and high strength at elevated temperatures (at 1000 centigrade, SiC is 7.5 times stronger than Al2O3). SiC has a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600 centigrade, and it does not melt at normal pressures but instead dissociates at 2600 centigrade.
Green silicon carbide is widely used for surface treatment such as abrasive blasting, sand blasting, lapping, microlapping, polishing, grinding, etc.
Description:
Green Silicon Carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke. It is a synthetic brittle carborundum with high thermal conductivity and high strength which get no decrease in 1000 centigrade (7.5 times stronger than Alumina)
