Silicon Metal is an indispensable industrial product, pivotal in steel-making, cast iron, aluminum (aviation, aircraft & automobile parts production), silicon optoelectronics, and multiple other industries. Revered as the 'salt' of modern industries, Metallic Silicon is crafted from high-purity quartz and coke in electric heating furnaces. Comprising approximately 98% silicon, this material exhibits minimal impurities, including iron, aluminum, and calcium, rendering it exceptionally pure and effective.
Silicon Metal lumps are produced via electric heating furnaces using quartz and coke. Through a redox process, quartz transitions into molten silicon liquid, which solidifies upon cooling, creating the initial, substantially large silicon metal lump.
These large lumps are then processed into smaller, more manageable pieces, known as standard sizes, ranging from 10-100mm.
This metal boasts a silver-gray or dark gray hue with a distinctive metallic luster. It features a high melting point, excellent heat resistance, elevated resistivity, and superior oxidation resistance, making it ideal for numerous applications.
1) Silicon Metal is extensively utilized in refractory materials and the power metallurgy industry to enhance heat resistance, wear resistance, and oxidation resistance.
2) In the chemical industry, industrial silicon powder serves as the foundational raw material for synthesizing high polymers of organic silicon.
3) Industrial silicon powder is transformed into monocrystalline silicon, a critical raw material in high-tech fields, especially for integrated circuits and electronic components.
4) In metallurgy and foundry sectors, industrial silicon powder acts as an additive in iron-based alloys and silicon steel, significantly improving steel's hardenability.
5) Silicon Metal is essential in producing high-temperature materials.
