Silicon Metal is an indispensable industrial marvel, extensively utilized in steel-making, cast iron, and aluminum industries, including aviation, aircraft, and automobile parts production. It also finds applications in silicon optoelectronic devices and numerous other sectors, earning the title of the "salt" of modern industries. Silicon Metal is crafted by smelting quartz and coke in an electric heating furnace, resulting in a product with approximately 98% silicon content. The remaining impurities include iron, aluminum, and calcium.
Silicon Metal lump is produced in electric heating furnaces using quartz and coke. Through a redox reaction, quartz transforms into molten silicon, which solidifies upon cooling to form the large primal silicon metal lumps.
These large primal silicon metal lumps are then processed into smaller, standardized sizes ranging from 10-100mm.
Characterized by its silver-gray or dark gray hue and metallic luster, Silicon Metal boasts a high melting point, exceptional heat resistance, high resistivity, and superior oxidation resistance.
1) Silicon Metal is widely applied in refractory materials and powder metallurgy industries to enhance heat resistance, wear resistance, and oxidation resistance.
2) In the chemical industry, Silicon Metal powder serves as a fundamental raw material for the formation of high polymer organic silicon compounds.
3) Industrial silicon powder is sublimated into monocrystalline silicon, an essential raw material for integrated circuits and electronic components in high-tech fields.
4) In metallurgy and foundry industries, Silicon Metal powder is utilized as an additive for iron base alloys and silicon steel, significantly improving steel hardenability.
5) Silicon Metal is crucial in the production of high-temperature materials.
