Product Description
Black silicon carbide is quartz sand, petroleumcoke in primary raw materials, smelting in the high temperature resistance furnace.
Green silicon carbide uses petroleum coke and the high quality silica as the main raw material, adding salt as additive, via high temperature electric resistance furnace smelting, the smelting into crystals of high purity, high hardness, its hardness is between fused alumina and diamond, and mechanical strength is higher than fused alumina.
Silicon carbide is suitable for processing hard alloy, glass, ceramic and non-metallic materials, are also used in the
semiconductor material, high temperature silicon carbide heating element, far infrared source base material, etc.
