Green silicon carbide is made of petroleum coke and high-quality silica as the main raw materials, adding salt as an additive, and smelted at high temperature in a resistance furnace. The smelted crystal has high purity and high hardness. Its hardness is between corundum and diamond, and its mechanical strength is high. higher than corundum. So what are the production processes and uses of green silicon carbide?

The microscopic shape is hexagonal crystals, the Mohs hardness of silicon carbide is 9.2, the microhardness of Vickers is 3000-3300 kg/mm2, the hardness of Knoop is 2670-2815 kg/mm, and the microhardness is 3300 kg per cubic millimeter.
Brown fused alumina mainly has four major application fields, namely: functional ceramics, refractory materials, abrasives and metallurgical raw materials.
White corundum abrasive is suitable for surface beautification treatment of various high-end products, crafts or hardware products. After sandblasting, the surface is white without any impurities, eliminating the trouble of cleaning. Fine white corundum can be used as the head of polishing and grinding.
