Size Range of silicon carbide F4-F220
Silicon carbide is produced in electrical internal resistance furnaces from high purity silica sands and petroleum coke,its combination of being very hard and sharp makes it a very aggressive abrasive.When produce green silicon carbide,will add industrial salt in it.
Purity and Size are the both main properties of silicon carbide,then what about the size range of silicon carbide F4-F220,now list for your reference as follows:
