Black silicon carbide is mainly made of quartz sand,petroleum coke,smelted by above
2500 in the electric furnace , the hardeness is tetween corundum and diamond,the hardness
is superior to corundum, it has the fuction of conductivity and thermal conductivity.
It is suitable to prosses metals and non-metallic materials.Such as gray cast iron,non-ferrous
metals, stone,leather,rubber and so on . It also widely used in refractories,metallurgical
additives.
