Silicon Carbide

Black silicon carbide is mainly made of quartz sand,petroleum coke,smelted by above 2500 in the electric furnace , the hardness is between corundum and diamond,the hardness is superior to corundum, it has the function of conductivity and thermal conductivity. It is suitable to process 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. Main Application: 1 .Abrasive Material: Black Silicon Carbide is suitable to grinding and cutting cast iron non-ferrous metal, leather ,rubber , wood ,plastic etc. It also can be made top grade refractories material ,silicon carbide has the characteristics of good stability ,equal particle size,high grinding and cutting and good wear resistance. It is mainly used to made sandpaper, abrasive belt, Whetstone, grinding blocks, grinding head, grinding paste and photovoltaic product
