Sillicon Carbide(SIC) is made from quartz sand and petroleum coke(smokeless acetylene) as the mainraw material.it is made via light resistance from hydrometallurgical,it is black opaque body hexagonal crystal and MOHS -hardness in the 915-9.5,which is after diamond and boron carbide with crisp and sharp performance and certain degree of conductive heat.
black silicon carbide is with sic purity 98% and the toughness is higher than green silicon carbide, mainly used for processing glass,ceramic,stone, refractory materials ,cast iron and other metal.
