Silicon Metal is an indispensable cornerstone of modern industry, essential in steel-making, cast iron, and aluminum applications such as aviation, aircraft, and automobile parts production. It also plays a crucial role in silicon optoelectronic devices and numerous other industries, earning its reputation as the 'salt' of contemporary industrial processes. Derived from the smelting of quartz and coke in electric furnaces, silicon metal boasts a primary silicon content of approximately 98%, with residual impurities including iron, aluminum, and calcium.
Silicon Metal lumps are formed in electric heating furnaces using quartz and coke. During the process, quartz undergoes a redox reaction, transforming into molten silicon liquid. Upon cooling, this liquid solidifies into the sizable primary silicon metal lumps we recognize.
These large lumps are subsequently broken down into smaller, standardized sizes, typically ranging from 10-100mm.
Characterized by its silver-gray or dark-gray hue and metallic luster, silicon metal exhibits a high melting point, excellent heat resistance, notable resistivity, and superior oxidation resistance.
1) Silicon Metal is extensively utilized in the refractory material and powder metallurgy industries to enhance heat resistance, wear resistance, and oxidation resistance.
2) In the organic silicon chemical sector, industrial silicon powder serves as a fundamental raw material for the formation of high-polymer organic silicon products.
3) Industrial silicon powder is sublimated to produce monocrystalline silicon, a vital component in the high-tech industry, particularly for integrated circuits and electronic elements.
4) Within metallurgy and foundry industries, industrial silicon powder acts as an additive in iron base alloys and as a key agent in silicon steel production, significantly improving the hardenability of steel.
5) Silicon metal is also integral to the creation of high-temperature materials.
