Silicon Metal is an essential industrial product used in high-performance steelmaking, cast iron, aluminum production (including aviation, aircraft, and automobile parts), silicon optoelectronic devices, and numerous other industries. Often referred to as the 'salt' of modern industry, silicon metal is produced by smelting quartz and coke in an electric heating furnace. Comprising approximately 98% pure silicon, with the remaining 2% being impurities such as iron, aluminum, and calcium, it is a fundamental component in various high-tech applications.
Silicon Metal lumps are produced in an electric heating furnace using quartz and coke. During the redox process, quartz transforms into molten silicon liquid, which solidifies upon cooling. The initial silicon metal lump formed is quite large and is subsequently processed
into smaller, standard-sized lumps ranging from 10-100mm. These smaller lumps are easier to handle and use.
Characterized by its silver-gray or dark gray metallic luster, Silicon Metal boasts a high melting point, excellent heat resistance, high resistivity, and superior oxidation resistance.
1) Silicon Metal is extensively applied in refractory materials and powder metallurgy industries to enhance heat resistance, wear resistance, and oxidation resistance.
2) In the chemical industry, industrial silicon powder serves as the foundational raw material for high polymers of organic silicon.
3) Industrial silicon powder is sublimated into monocrystalline silicon, a critical raw material in high-tech fields for integrated circuits and electronic components.
4) In metallurgy and foundry, industrial silicon powder is used as an additive in iron-base alloys and silicon steel, significantly improving steel's hardenability.
5) Silicon metal is integral in the production of high-temperature materials, where its properties are indispensable.
