Silicon Metal is an exceptionally vital industrial product with diverse applications in steel-making, cast iron, and aluminum for aviation, aircraft, and automobile parts production. It also finds usage in silicon optoelectronic devices and many other industries, earning it the title the 'salt' of modern industries. This metal silicon is derived from smelting quartz and coke in electric heating furnaces, with a silicon content of approximately 98%. The remaining impurities include iron, aluminum, and calcium.
Silicon Metal lumps are produced in electric heating furnaces using quartz and coke. The quartz undergoes redox reactions, transforming into molten silicon liquid. Upon cooling, it solidifies into the large, primal silicon metal lumps we see. These large lumps are then
processed into smaller, standard-sized lumps, typically ranging from 10-100mm.
Silicon Metal exhibits a silver-gray or dark gray hue with a metallic luster. It boasts a high melting point, excellent heat resistance, high resistivity, and superior oxidation resistance.
1) Silicon Metal is widely applied in the refractory material and powder metallurgy industries to enhance heat resistance, wear resistance, and oxidation resistance.
2) In the chemical industry, industrial silicon powder serves as the fundamental raw material for high polymers of organic silicon.
3) Industrial silicon powder is sublimated into monocrystalline silicon, an essential material in high-tech fields for integrated circuits and electronic components.
4) In metallurgy and foundry industries, industrial silicon powder is considered a crucial additive to iron base alloys and a key ingredient in silicon steel production, thus improving steel's hardenability.
5) Silicon metal is integral in the production of high-temperature materials.
Our main products include ferromanganese, metallic silicon, silicon carbon alloy, cored wire, ferrochrome, silicon manganese alloy, silicon carbide, ferrosilicon, silicon aluminum barium calcium, and silicon barium calcium. We also engage in the export of refractory materials and other metallurgical products, customizing processes to meet customer needs.
