Green silicon carbide is made of petroleum coke and silica as the main raw materials through high temperature smelting. Green silicon carbide is higher than corundum in abrasives and second only to diamond, cubic boron nitride and boron carbide. Its manufacturing method is the same as black silicon carbide, but the The purity of raw materials is high, and the physical properties are similar to black silicon carbide, but the performance is slightly more brittle than black, and it has better thermal conductivity and semiconductor characteristics.
Using silicon carbide has the characteristics of corrosion resistance, high temperature resistance, high strength, good thermal conductivity, impact resistance, etc., silicon carbide can be used for various smelting furnace linings, high temperature furnace components, silicon carbide plates, linings, supports, saggers, etc. , Silicon carbide crucible, etc.
On the other hand, it can be used for high-temperature indirect heating materials in non-ferrous metal smelting industry, such as vertical tank distillation furnace, rectification furnace tray, aluminum electrolytic cell, copper melting furnace lining, arc plate for zinc powder furnace, thermocouple protection tube, etc. ; Used to make high-grade silicon carbide ceramic materials such as wear resistance, corrosion resistance and high temperature resistance; 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 for highways and aviation runways.
The follow-up market direction of green silicon carbide is mainly for the segment sand and granular sand market, and the micro powder is mainly for the semiconductor, magnetic material, piezoelectric crystal and other markets. As a superconducting material and a high-energy-carrying material, green silicon carbide will play an important role in China's future 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. Due to the relatively large demand for green silicon carbide in the electronics industry, the electronics industry will become a huge market in the future.
