Silicon Metal is an indispensable industrial powerhouse, vital for steel-making, cast iron, aluminum (aviation, aircraft & automobile parts production), silicon optoelectronic devices, and countless other industries. Often hailed as the 'salt' of modern industries, metal silicon is derived from quartz and coke through electric furnace smelting. Boasting a silicon content of approximately 98%, it includes minor impurities like iron, aluminum, and calcium.
Silicon Metal lumps are created in an electric heating furnace using quartz and coke. The quartz undergoes a redox reaction, transforming into molten silicon liquid. Upon cooling, it solidifies into large primal silicon metal lumps.
These primal silicon metal lumps are then processed into smaller, standard-sized lumps, ranging from 10-100mm.
This product is characterized by its silver-gray to dark-gray hue, metallic luster, high melting point, excellent heat resistance, high resistivity, and superior oxidation resistance.
1) Widely 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 a foundational raw material for high-polymer organic silicon formation.
3) Sublimated into monocrystalline silicon, this industrial powder is crucial in high-tech sectors, acting as an essential raw material for integrated circuits and electronic components.
4) In metallurgy and foundry, industrial silicon powder is used as an iron base alloy additive and silicon steel alloy agent, thereby improving steel's hardenability.
5) Essential in the production of high-temperature resistant materials.
Our extensive product range includes ferromanganese, metallic silicon, silicon carbon alloy, cored wire, ferrochrome, silicon manganese alloy, silicon carbide, ferrosilicon, silicon aluminum barium calcium, silicon barium calcium, among others.
