Silicon Metal is an indispensable industrial marvel, integral to steel-making, cast iron, aluminum (including aviation, aircraft, and automobile parts production), and silicon optoelectronic devices, among many other industries. Often hailed as the 'salt' of modern industries, metallic silicon is crafted from quartz and coke through electric heating furnace smelting. The primary ingredient, silicon, boasts a high concentration of approximately 98%, with minor impurities such as iron, aluminum, and calcium.
Silicon Metal lumps are birthed from the smelting of quartz and coke in electric heating furnaces. The quartz undergoes a redox process, transforming into molten silicon liquid. Once cooled, this liquid solidifies into large primal silicon metal lumps.
These large silicon lumps are then meticulously processed into smaller, standardized sizes, ranging from 10-100mm, ensuring optimal usability.
Characterized by its silver-gray or dark gray hue with a metallic sheen, Silicon Metal boasts a high melting point, exceptional heat resistance, impressive resistivity, and superior oxidation resistance.
1) Silicon Metal is widely utilized in refractory materials and powder metallurgy, significantly enhancing heat resistance, wear resistance, and oxidation resistance.
2) In the realm of organic silicon chemistry, industrial silicon powder serves as a foundational raw material for the formation of high polymers of organic silicon.
3) Industrial silicon powder is vital in the high-tech sector, being sublimated into monocrystalline silicon, an essential raw material for integrated circuits and electronic components.
4) In metallurgy and foundry, industrial silicon powder is esteemed as an iron base alloy additive and a crucial component in silicon steel alloys, thereby boosting steel's hardenability.
5) Silicon Metal is also pivotal in the creation of high-temperature materials.
