Silicon Metal is an indispensable industrial product with versatile applications in steel-making, cast iron, aluminum (essential for aviation, aircraft & automobile parts production), as well as in silicon optoelectronic devices and numerous other industries. Revered as the 'salt' of modern industries, metal silicon is produced from quartz and coke through electric heating furnace smelting. The primary ingredient-silicon-constitutes approximately 98%, with the remainder comprising impurities such as iron, aluminum, and calcium.
Silicon Metal lumps are produced in electric heating furnaces using quartz and coke. Through a redox reaction, quartz becomes molten silicon, which solidifies upon cooling. Initially formed into large primal lumps, the silicon metal is subsequently processed.
into smaller, standard-sized lumps, ranging from 10-100mm.
This silicon metal is characterized by its silver-gray or dark gray hue with a metallic luster. It boasts a high melting point, exceptional heat resistance, high resistivity, and superior oxidation resistance.
1) Widely utilized in refractory materials and powder metallurgy industries to enhance heat resistance, wear resistance, and oxidation resistance.
2) Serves as a basic raw material in the chemical industry for the production of organic silicon, an essential component in high polymer organic silicon formations.
3) Industrial silicon powder is converted into monocrystalline silicon, a critical raw material for integrated circuits and electronic components in high-tech fields.
4) In metallurgy and foundry, industrial silicon powder is valued as an iron-base alloy additive and an alloy pharmaceutical for silicon steel, boosting steel hardenability.
5) Integral to the production of high-temperature materials.
