Products Introduction: Black silicon carbide is made from quartz sand and smokeless acetylene as the main raw material.It is made via light resistance from hydrometallurgical,it is black opaque body hexagonal crystal and MOHS-hardness in the 9.15,which is after diamond and boron carbide with crisp and sharp performance and certain degree of conductive heat.Black silicon carbide is higher toughness than green silicon carbide with sic purity 98%, it have been used for processing glass,refractory materials,ceramic,stone,cast iron and other metal. Advantages of sicheng silicon carbide:Price of 98.5% abrasive Black silicon carbide (1) Special treated products get higher purity, better toughness, and better grinding effect (2) Higher purity and less impurities (3) Chemical washed and water washed good cleanness. (4) Good hardness,Corrosion resistance
