Silicon Metal is an indispensable and versatile industrial marvel used extensively in steel-making, cast iron, aluminum (aviation, aircraft & automobile parts production), and silicon optoelectronic device industries among others. Often referred to as the "salt" of modern industries, metal silicon is derived from the smelting of quartz and coke in an electric heating furnace. It comprises approximately 98% silicon content, with trace impurities including iron, aluminum, and calcium.
Silicon Metal lumps are synthesized in an electric heating furnace using quartz and coke. The quartz undergoes redox reactions, transforming into molten silicon liquid. Upon cooling, this liquid solidifies into large primal silicon metal lumps.
These large lumps are subsequently processed into smaller, standard-sized lumps ranging from 10-100mm.
With a silver-gray or dark gray hue and a metallic luster, silicon metal boasts a high melting point, exceptional heat resistance, substantial resistivity, and superior oxidation resistance.
1) Widely utilized in refractory materials and powder metallurgy industries to enhance heat resistance, wear resistance, and oxidation resistance.
2) In chemical industries, industrial silicon powder serves as the foundational raw material for the synthesis of high polymers of organic silicon.
3) Industrial silicon powder is sublimated into monocrystalline silicon, a cornerstone in high-tech fields, essential for integrated circuits and electronic components.
4) In metallurgy and foundry sectors, industrial silicon powder is a valued additive in iron base alloys and silicon steel, significantly improving steel hardenability.
5) Silicon metal is crucial in the manufacture of high-temperature materials.
