Hijau silikon karbida is made of petroleum coke and silica as the main raw materials through high-temperature smelting. Among abrasives, green silicon carbide is higher than corundum and second only to diamond, cubic boron nitride and boron carbide. Its manufacturing method is the same as that of black silicon carbide, but the purity of the raw materials used is higher. Its physical properties are similar to those of black silicon carbide, but it is slightly more brittle than black silicon carbide and has better thermal conductivity and semiconductor properties.
Silicon carbide has the characteristics of corrosion resistance, high temperature resistance, high strength, good thermal conductivity and impact resistance. On the one hand, silicon carbide can be used for various smelting furnace linings, high-temperature furnace components, silicon carbide plates, linings, supports, saggers, silicon carbide crucibles, etc. On the other hand, it can be used for high-temperature indirect heating materials in the non-ferrous metal smelting industry, such as vertical tank distillation furnaces, distillation furnace trays, aluminum electrolytic cells, copper melting furnace linings, arc plates for zinc powder furnaces, thermocouple protection tubes, etc.; it can be used to make advanced silicon carbide ceramic materials that are wear-resistant, corrosion-resistant, and high-temperature resistant; it can also be used to make rocket nozzles, gas turbine blades, etc. In addition, silicon carbide is also one of the ideal materials for solar water heaters on highways and aviation runways.
The subsequent market direction of green silicon carbide is mainly for the segmented sand and granular sand markets, and the micro powder is mainly for the semiconductor, magnetic material, piezoelectric crystal and other markets. As a superconducting material and high energy-carrying material, green silicon carbide will play an important role in the future fields of material science, aerospace and Internet technology.
In recent years, with the continuous development of electronic technology, green silicon carbide has also been widely used in the electronics industry. Since the electronics industry has a large demand for green silicon carbide, the electronics industry will become a huge market in the future.
