Silicon Metal is a pivotal industrial product, renowned for its versatility in steel-making, cast iron, and aluminum industries, crucial for manufacturing aircraft, automobile parts, and silicon optoelectronic devices. Hailed as the 'salt' of modern industries, this high-value product is derived from quartz and coke, meticulously smelted in electric furnaces. Silicon Metal boasts a silicon content of approximately 98%, with minimal impurities such as iron, aluminum, and calcium.
Silicon Metal lumps are produced in electric furnaces through the redox reaction of quartz and coke, resulting in molten silicon liquid. Once cooled, the molten silicon solidifies into large primal silicon metal lumps.
These large lumps are then processed into smaller, standardized sizes of 10-100mm, known as Silicon Metal Lumps.
Displaying a striking silver-gray or dark gray hue with a metallic luster, Silicon Metal features a high melting point, exceptional heat resistance, high resistivity, and superior oxidation resistance.
1) Silicon Metal is extensively utilized in refractory materials and powder metallurgy industries to enhance heat resistance, wear resistance, and oxidation resistance.
2) In the chemical industry, industrial silicon powder serves as a foundational raw material for the synthesis of high polymers in organic silicon.
3) Industrial silicon powder is transformed into monocrystalline silicon, an indispensable material in high-tech fields for integrated circuits and electronic components.
4) In metallurgy and foundry industries, industrial silicon powder is esteemed as an iron base alloy additive, enhancing the hardenability of steel through silicon steel alloying.
5) Silicon Metal is integral to the production of high-temperature materials.
