Size range of green silicon carbide F4-F220
Green Silicon Carbide is produced in electrical internal resistance furnaces from silica sands and petroleum coke(added salt during smelting),with high hardness,thermal conductivity and strength.
Purity and Particle size distribution are the two main factors to decide the quality of green silicon carbide,now list the size range of green silicon carbide F4-F220 for reference as follow:
