Silicon Metal is a cornerstone of modern industry, finding critical applications in steel-making, cast iron, aluminum (aviation, aircraft, and automobile parts production), silicon optoelectronic devices, and more. Known as the 'salt' of modern industries, this material is crafted from quartz and coke in electric heating furnaces. Boasting a silicon content of approximately 98%, it includes minor impurities such as iron, aluminum, and calcium.
Our premium Silicon Metal lump is produced in an electric heating furnace using quartz and coke. Through a redox process, quartz transforms into molten silicon, which solidifies upon cooling into the large primal silicon metal lumps.
These large lumps are then processed into smaller, standard-sized pieces, typically ranging from 10-100mm.
Featuring a striking silver-gray or dark-gray hue with a metallic luster, our Silicon Metal boasts a high melting point, exceptional heat resistance, high resistivity, and superior oxidation resistance.
1) Silicon Metal is extensively applied 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 the foundational raw material for high-performance organic silicon polymers.
3) Industrial silicon powder is sublimated into monocrystalline silicon, a vital raw material in the high-tech sector for integrated circuits and electronic components.
4) In metallurgy and foundry applications, industrial silicon powder is used as an iron base alloy additive and a silicon steel pharmaceutical, significantly improving steel hardenability.
5) Silicon metal is indispensable in the production of high-temperature materials.
Our diverse product range includes 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, offering processing tailored to customer specifications.
Equipped with a 206 cubic meter blast furnace, two 12500 kVA submerged arc furnaces, two 3600 kVA refining furnaces, four medium frequency electric furnaces, and three cladding line production lines, our company achieves optimal production efficiency. This combination guarantees a seamless process for producing high-quality manganese series products with high yield and low consumption.
