Classification of silicon carbide

Including black and green silicon carbide, silicon carbide, which: SiC is black quartz sand, H&X silicon carbide manufacturers coke and quality silica as the main raw materials, smelting electric arc furnace. Its hardness between corundum and diamond, corundum higher mechanical strength, brittle and sharp. Green silicon carbide based petroleum coke and quality silica as the main raw material, add salt as an additive, smelting electric arc furnace. Hardness between corundum and diamond, corundum higher mechanical strength. There are commonly two different silicon carbide abrasive H&X white fused alumina supplier, one is green silicon carbide, containing more than SiC 97%, the hard gold is mainly used for grinding tools. Another black silicon carbide, metallic luster, containing more than SiC 95%, the large intensity ratio of green silicon carbide, but lower hardness, primarily used for grinding cast iron and non-metallic materials.
