Silicon Metal is an indispensable industrial product used in steel-making, cast iron, aluminum (for aviation, aircraft & automotive parts), silicon optoelectronics, and various other industries. Often referred to as the 'salt' of modern industries, this metal silicon is produced by smelting quartz and coke in an electric heating furnace. The primary silicon content is approximately 98%, with impurities like iron, aluminum, and calcium constituting the remainder.
Silicon Metal lumps are produced in electric heating furnaces using quartz and coke. Through a redox reaction, quartz transforms into molten silicon, which solidifies upon cooling to form large primal silicon metal lumps. These are then
processed into smaller, standard-sized lumps measuring 10-100mm.
Silver-gray or dark gray with a metallic luster, Silicon Metal boasts a high melting point, excellent heat resistance, high resistivity, and superior oxidation resistance.
1) Widely applied in refractory materials and the power metallurgy industry, Silicon Metal enhances heat resistance, wear resistance, and oxidation resistance.
2) In the chemical industry, 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 material in high-tech fields for integrated circuits and electronic components.
4) In metallurgy and foundries, industrial silicon powder is used as an iron base alloy additive, improving the hardenability of steel.
5) Silicon metal is vital for producing high-temperature materials.
Our principal 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 export refractory materials and other metallurgical products. Custom processing is available to meet client specifications.
The company operates a 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 for cladding. This setup facilitates a seamless manganese series hot charging and hot mixing system, ensuring a one-stop production process characterized by high quality, high yield, and low consumption.
