Silicon Metal is an indispensable titan of the industrial world. This versatile product plays a crucial role in steel-making, cast iron production, and the creation of aluminum components for aviation, aircraft, and automobiles. It is also vital in the fabrication of silicon optoelectronic devices and numerous other industries, earning its nickname as the 'salt' of modern industries. Crafted from quartz and coke through electric furnace smelting, Shining Grey Silicon Metal 441 boasts a silicon content that majestically reaches around 98%, with the remaining portion composed of carefully controlled impurities like iron, aluminum, and calcium.
Born from an electric heating furnace, Silicon Metal lump is meticulously crafted by the redox reaction of quartz and coke. This process transforms quartz into a molten silicon liquid, which solidifies upon cooling into large primal silicon metal lumps. These raw formations are then skillfully refined
into more manageable pieces known as standard size lumps, ranging from 10mm to 100mm. This transformation allows for easier handling and utilization across various applications.
Exhibiting a lustrous silver gray or dark gray sheen, Shining Grey Silicon Metal 441 is not only about looks. It offers a formidable high melting point, exceptional heat resistance, significant resistivity, and superior oxidation resistance, making it a superior choice for demanding industrial applications.
1) Silicon Metal serves as a vital component in the refractory material and power metallurgy industries, renowned for its ability to significantly enhance heat resistance, wear resistance, and oxidation resistance.
2) In the realm of organic silicon chemistry, industrial silicon powder stands as a fundamental raw material pivotal to the formation of high polymer organic silicon products.
3) Industrial silicon powder undergoes sublimation into monocrystalline silicon, a critical element in the high-tech industry, indispensable as a primary raw material for integrated circuits and electronic components.
4) In metallurgy and foundry applications, industrial silicon powder is esteemed as an iron base alloy additive and serves as the alloy pharmaceutical in silicon steel, thereby enhancing the hardenability of steel.
5) Silicon metal plays a crucial role in the manufacturing of high-temperature materials, contributing significantly to their development.
