Silicon Metal is an indispensable industrial marvel, extensively utilized in steel-making, cast iron, aluminum production (aviation, aircraft & automobile parts), silicon optoelectronic devices, and numerous other sectors. Revered as the 'salt' of modern industries, silicon metal is crafted from quartz and coke in high-heat electric furnaces. With a silicon content of approximately 98%, the remaining impurities include iron, aluminum, and calcium.
Silicon Metal lumps are meticulously produced in electric furnaces using quartz and coke. The redox process converts quartz into molten silicon, which upon cooling forms solid lumps. Initially, these lumps are massive.
They are then expertly processed into standard-sized lumps, ranging from 10-100mm. These Silicon Metal Lumps are ready to meet diverse industrial needs.
Exhibiting a silver-gray to dark gray hue, Silicon Metal boasts a metallic luster, high melting point, excellent heat resistance, high resistivity, and superior oxidation resistance.
1) Widely utilized in refractory materials and powder metallurgy to enhance heat resistance, wear resistance, and oxidation resistance.
2) Essential in chemical industries, where industrial silicon powder serves as a fundamental raw material for the creation of high polymers in organic silicon formations.
3) Industrial silicon powder is transformed into monocrystalline silicon, a key material in high-tech fields, indispensable for integrated circuits and electronic components.
4) In metallurgy and foundry sectors, it acts as a vital iron base alloy additive and alloy pharmaceutical for silicon steel, significantly boosting steel hardenability.
5) Integral in manufacturing high-temperature materials.
Our primary offerings include ferromanganese, metallic silicon, silicon carbon alloy, cored wire, ferrochrome, silicon manganese alloy, silicon carbide, ferrosilicon, silicon aluminum barium calcium, and silicon barium calcium.
