Silicon Metal stands as an indispensable industrial cornerstone, integral to steel-making, cast iron, and aluminum industries, including aviation, aircraft, and automobile parts production. It also finds applications in silicon optoelectronic devices and many other sectors, earning its title as the 'salt' of modern industries. Derived from quartz and coke, Silicon Metal boasts a silicon content of approximately 98%, with trace impurities of iron, aluminum, and calcium.
Formed in an electric heating furnace, Silicon Metal begins its journey from quartz and coke. Quartz undergoes a redox reaction, transforming into molten silicon liquid. Upon cooling, it crystallizes into solid lumps.
These large primal lumps are subsequently broken down into smaller, standard-sized lumps, typically ranging from 10-100mm.
Featuring a captivating silver-grey or dark grey hue with a metallic luster, Silicon Metal is celebrated for its high melting point, excellent heat resistance, superior oxidation resistance, and high resistivity.
1) Silicon Metal is extensively used in refractory materials and the power metallurgy industry to enhance heat, wear, and oxidation resistance.
2) In the realm of organic silicon chemistry, industrial silicon powder serves as a foundational raw material for high polymers in organic silicon formulations.
3) Sublimated into monocrystalline silicon, industrial silicon powder is crucial in high-tech fields, serving as an essential raw material for integrated circuits and electronic components.
4) In metallurgy and foundry sectors, industrial silicon powder is esteemed as an iron-base alloy additive, enhancing steel's hardenability, and as a pivotal ingredient in silicon steel alloys.
5) Silicon metal is a key component in the production of high-temperature materials.
