| Silicon carbide is an inorganic substance with a chemical formula of SiC. It is made by high temperature smelting of raw materials such as quartz sand, petroleum coke (or coal coke), and wood chips (salt is needed to produce green silicon carbide) through a resistance furnace. Silicon carbide also exists in nature, a rare mineral, moissanite. Among the non-oxide high-tech refractory materials such as C, N, and B, silicon carbide is the most widely used and most economical one. Green silicon carbide is made from petroleum coke and high-quality silica as the main raw material, adding salt as an additive, and smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, and its mechanical strength is higher than that of corundum. |

| The Usage of Silicon carbide: 1. In the electrical industry, silicon carbide can be used as lightning arrester valve body, silicon carbon electric heating element, far infrared generator, etc. 2. In the aerospace industry, gas filters and combustion chamber nozzles made of silicon carbide have been used in rocket technology. 3. Low-grade silicon carbide can be used as steelmaking deoxidizer and cast iron additive. 4. In the carbon industry, silicon carbide can be used to produce bricks for iron-making blast furnaces, such as graphite silicon carbide, silicon carbide bricks combined with silicon nitride, etc. 5. In the production of graphite electrodes, silicon carbide is also used as the coating refractory sintering material of oxidation-resistant coating electrodes to add the coating's ability to withstand sharp changes in temperature. 6. In the manufacture of special carbon materials-biochar, propane and trichloromethylsilane are often used as gas materials. After high temperature pyrolysis, the silicon-containing pyrolytic carbon coating is accumulated on the graphite substrate to add products. The hardness, strength and wear resistance. |
Packing for Green Silicon carbide: It is packaged in 25kg bag then in 1ton Jumbo bag.
