Structure of Silicon Carbide Description
Silicon Carbide is made by a precision water classification process and air flow classification using material that is produced from the reaction between high purity silica sand and petroleum coke in a resistance-type furnace. Measuring 9.0+ on the MOHS scale of hardness, silicon carbide is one of the hardest abrasives known in the industry. The inherent friability of the sharp crystalline structure assures the continuous exposure of new cutting edges, which produces a faster and cleaner cutting performance.Silicon Carbide powders are precisely graded to the particle size specifications set forth by the European FEPA “F” Microgrit Standard.Silicon Carbide powders are also available in sizes that are graded to the “JIS” Japanese Industrial Standard. Material is available in both Black and Green color.
Usage
It is widely used for steelmaking, foundry, refractory and for abrasive.
