Silicon Metal is an indispensable industrial product that finds extensive applications in steel-making, cast iron, aluminum (aviation, aircraft & automobile parts production), silicon optoelectronic devices, and many other industries. Often termed as the 'salt' of modern industries, this product is crafted from quartz and coke through electric furnace smelting. The primary component is silicon, comprising about 98%, with minor impurities like iron, aluminum, and calcium.
Silicon Metal lumps are produced in an electric heating furnace using quartz and coke. Through a redox reaction, quartz transforms into molten silicon liquid. Upon cooling, it solidifies into large primal silicon metal lumps. Subsequent processing reduces these lumps.
into smaller, standardized sizes. The final Silicon Metal Lumps range from 10-100mm.
Boasting a silver-gray or dark-gray metallic luster, Silicon Metal exhibits a high melting point, excellent heat resistance, high resistivity, and superior oxidation resistance.
1) Silicon Metal is extensively used in the refractory material and powder metallurgy industries to enhance heat resistance, wear resistance, and oxidation resistance.
2) In the realm of organic silicon chemistry, industrial silicon powder serves as a fundamental raw material for high polymers of organic silicon.
3) Industrial silicon powder is sublimated into monocrystalline silicon, a crucial raw material in high-tech fields for integrated circuits and electronic components.
4) In metallurgy and foundry, industrial silicon powder is utilized as an additive in iron-based alloys and as a silicon steel alloy pharmaceutical, thereby enhancing steel's hardenability.
5) Silicon Metal is instrumental in the production of high-temperature materials.
