silicon carbide F4-F220 mean diameter
Silicon Carbide is produced in electrical internal resistance furnaces from silica sands and petroleum coke(added salt during smelting when produce green silicon carbide),with high hardness,thermal conductivity and strength.
Silicon carbide includes black silicon carbide and green silicon carbide,they both have the same particle size distibution and mean diameter.
Silicon carbide F4-F220 mean diameter is as follows:
