Silicon Carbide Powder For Refractory Material   Applications
 (1) Silicon carbide can be use as metallurgical deoxidizer and high temperature resistant materials in smelting.
 (2) It can also be use as abrasive, which can  be used to make abrasive tools, such as grinding  wheels, oilstones, grinding head and so on.
 
 Advantages
 (1) Large melting furnace, longer melting time, lead to more crystallization, bigger crystals, higher purity and less impurities.
 (2) Good hardness, longer life.
 (3) Chemical washed and water washed, good cleanness.
 (4) Special treated products get higher purity, better toughness, and better grinding effect.
