SIC is made from quartz sand and petroleum coke(smokeless acetylene) （salt added in the produce of green silicon carbide) 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
