Silicon Carbide Sand 98% is made of quartz sand, petroleum coke (or coal coke), wood chips (need to add salt when producing green silicon carbide) and other raw materials in the resistance furnace by high-temperature smelting.
At present, China's industrial production of silicon carbide is divided into two types of black silicon carbide and green silicon carbide, are hexagonal crystals, the specific gravity of 3.20 ~ 3.25, microhardness of 2840 ~ 3320kg/mm2.
Silicon Carbide Sand 98% is based on petroleum coke and high-quality silica as the main raw material. It is added with salt as an additive, and it is produced through high-temperature smelting in resistance furnaces. Its hardness is between corundum and diamond, and its mechanical strength is higher than that of corundum.
Silicon Carbide Sand 98% is made of quartz sand, petroleum coke and high-quality silica as the main raw material, which is produced by high-temperature smelting in electric resistance furnace. Its hardness is between corundum and diamond, mechanical strength is higher than corundum, brittle and sharp.
