[0002] The production method of green silicon carbide powder is basically the same as that of black silicon carbide, except for the different requirements on raw materials. Green silicon carbide is made of petroleum coke and high-quality silica as the main raw materials, and salt is added as an additive. It is smelted at high temperature in a resistance furnace. The smelted crystals are of high purity and high hardness. Its hardness is between corundum and diamond, and its mechanical strength is higher than that of corundum. The manufacturing method of green silicon carbide is the same as that of black silicon carbide, but the purity of the raw materials used is higher. It is also formed at a high temperature of about 2200°C in a resistance furnace. It is green, translucent, and hexagonal. Its Sic content is higher than that of black. Its physical properties are similar to those of black silicon carbide, but its performance is slightly more brittle than that of black.
