Silicon Metal is an essential industrial product used in steel-making, cast iron, aluminum (for aviation, aircraft, and automobile parts production), silicon optoelectronic devices, and numerous other industries. Known as the "salt" of modern industries, silicon metal is produced from quartz and coke in electric heating furnaces. The primary ingredient is silicon, with a content of about 98%. The remaining impurities include iron, aluminum, and calcium.
Silicon Metal lumps are produced in electric heating furnaces using quartz and coke. The quartz undergoes a redox reaction, transforming into molten silicon liquid. Once cooled, it solidifies into the large primal silicon metal lump.
These large lumps are then broken down into smaller standard-sized lumps, typically ranging from 10-100mm.
The silicon metal lumps exhibit a silver gray or dark gray color with a metallic luster. They feature a high melting point, excellent heat resistance, high resistivity, and superior oxidation resistance.
1) Silicon Metal is widely used in refractory materials and the power metallurgy industry to enhance heat resistance, wear resistance, and oxidation resistance.
2) In the chemical industry, specifically in organic silicon production, industrial silicon powder serves as a fundamental raw material for forming high polymers of organic silicon.
3) Industrial silicon powder is sublimated into monocrystalline silicon, playing a crucial role in high-tech fields as an essential raw material for integrated circuits and electronic components.
4) In metallurgy and foundry applications, industrial silicon powder is used as an additive in iron-based alloys and as an alloying agent in silicon steel, thereby enhancing the steel's hardenability.
5) Silicon metal is also utilized in the production of high-temperature materials.
