Silicon Metal is an indispensable industrial marvel, pivotal in steel-making, cast iron, aluminum production (aviation, aircraft, and automobile parts), silicon optoelectronic devices, and numerous other industries. Revered as the 'salt' of modern industries, Silicon Metal is synthesized from quartz and coke in an electric furnace. Boasting a primary silicon content of approximately 98%, the remaining impurities include iron, aluminum, and calcium.
Silicon Metal lumps are crafted in electric heating furnaces using quartz and coke. The redox reaction transforms quartz into molten silicon, which solidifies upon cooling. Initially, the Silicon Metal lump is substantial in size.
These large Silicon Metal lumps are then processed into smaller, standard-sized chunks ranging from 10-100mm.
Displaying a silver-gray or dark gray hue with a metallic sheen, Silicon Metal is renowned for its high melting point, excellent heat resistance, elevated resistivity, and exceptional oxidation resistance.
1) Silicon Metal is extensively used in refractory materials and the power metallurgy industry to enhance heat resistance, wear resistance, and oxidation resistance.
2) In the realm of organic silicon chemistry, industrial silicon powder serves as the foundational raw material for high polymers.
3) Industrial silicon powder is sublimated to produce monocrystalline silicon, a critical raw material for integrated circuits and electronic components in high-tech applications.
4) In metallurgy and foundry sectors, industrial silicon powder acts as an additive in iron-based alloys, enhancing the hardenability of silicon steel.
5) Silicon metal is also pivotal in the production of high-temperature materials.
