Silicon Metal is a crucial industrial product with diverse applications including steel-making, cast iron, aluminum manufacturing (aviation, aircraft & automobile parts production), and silicon optoelectronic devices. Renowned as the "salt" of modern industries, it is produced from quartz and coke in electric heating furnaces. The primary ingredient, silicon, constitutes about 98%, with the remainder being impurities such as iron, aluminum, and calcium.
Silicon Metal lumps are produced in electric heating furnaces by the redox reaction of quartz and coke, transforming into molten silicon liquid. Upon cooling, this liquid solidifies into large primal silicon metal lumps.
These large primal lumps are further processed into smaller standard-sized lumps, ranging from 10-100mm, for ease of use.
Characterized by its silver gray or dark gray metallic luster, Silicon Metal boasts a high melting point, exceptional heat resistance, high resistivity, and superior oxidation resistance.
1) Widely utilized in refractory materials and power metallurgy industries, 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 the formation of high polymers of organic silicon.
3) Sublimated into monocrystalline silicon, industrial silicon powder is indispensable in high-tech fields, serving as a critical raw material for integrated circuits and electronic components.
4) In metallurgy and foundry, industrial silicon powder acts as an iron base alloy additive, enhancing the hardenability of steel through its role as an alloy pharmaceutical of silicon steel.
5) Silicon Metal is essential in the production of high-temperature materials.
