Silicon Metal is a pivotal industrial product utilized in steel-making, cast iron, and aluminum industries, including aviation, aircraft, and automobile parts production. It also finds applications in silicon optoelectronic devices and numerous other industries, earning the moniker 'salt' of modern industries. Produced from quartz and coke in electric heating furnaces, metal silicon boasts a silicon content of approximately 98%, with the remainder consisting of trace impurities like iron, aluminum, and calcium.
Silicon Metal lumps are produced in an electric heating furnace using quartz and coke. Quartz undergoes a redox reaction, transforming into molten silicon liquid which solidifies upon cooling into the large primal silicon metal lumps we recognize.
These large primal silicon metal lumps are then processed into smaller, standard-size lumps measuring 10-100mm.
Silicon Metal is characterized by its silver-gray or dark gray hue with a metallic luster. It has a high melting point, excellent heat resistance, high resistivity, and superior oxidation resistance.
1) Silicon Metal is extensively used in refractory materials and powder metallurgy industries to enhance heat resistance, wear resistance, and oxidation resistance.
2) In the field of organic silicon chemistry, industrial silicon powder serves as the fundamental raw material for the formation of high polymers.
3) Industrial silicon powder is elevated to monocrystalline silicon, making it an indispensable raw material in high-tech fields for integrated circuits and electronic components.
4) In metallurgy and foundry, industrial silicon powder is valued as an iron base alloy additive and silicon steel alloy constituent, improving the hardenability of steel.
5) Silicon Metal is crucial in the production of high-temperature materials.
Our core products include ferromanganese, metallic silicon, silicon carbon alloy, cored wire, ferrochrome, silicon manganese alloy, silicon carbide, ferrosilicon, and silicon aluminum barium calcium, among others. We also engage in the exportation of refractory materials and other metallurgical products, with the capability to customize products per customer specifications.
The company boasts advanced infrastructure, including one 206 cubic meter blast furnace, two 12500 kVA submerged arc furnaces, two 3600 kVA refining furnaces, four medium-frequency electric furnaces, and three production lines. This setup facilitates the efficient operation of manganese series hot charging and hot mixing systems, enabling a seamless, one-stop production process that emphasizes high quality, high yield, and low consumption.
