Abrasives black silicon carbide powder

Product Description Abrasives black silicon carbide powder 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.Abrasives black silicon carbide powder 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. Raw Material Quartz sand and coal coke (petroleum coke) are produced by high temperature smelting in resistance furnace. Density:3.2g/cm3 Produce Processing Quartz sand , coal coke (petroleum coke) and sodium chloride are produced by high temperature smelting in resistance furnace.
