Silicon Metal is an indispensable industrial marvel, essential in steel-making, cast iron, aluminum (critical for aviation, aircraft, and automobile parts production), silicon optoelectronic devices, and numerous other sectors. Often hailed as the 'salt' of modern industry, metal silicon is derived from quartz and coke through electric furnace smelting. With a primary silicon content of approximately 98%, the remaining impurities include iron, aluminum, and calcium, ensuring unparalleled performance.
Silicon Metal lump production involves the sophisticated process of smelting quartz and coke in an electric heating furnace. The quartz undergoes reduction-oxidation to transform into molten silicon liquid, which solidifies upon cooling. Initially, silicon metal lumps are quite large; they are then
processed into smaller, standardized sizes, typically ranging from 10-100mm, providing versatility for various industrial applications.
Boasting a silver-gray or dark gray hue with a metallic sheen, Silicon Metal Lump is distinguished by its high melting point, superior heat resistance, excellent resistivity, and remarkable oxidation resistance.
1) Silicon Metal is extensively utilized in refractory materials and power metallurgy sectors to enhance heat, wear, and oxidation resistance.
2) In the realm of organic silicon chemistry, industrial silicon powder serves as a foundational raw material for high polymer organic silicon formulations.
3) Industrial silicon powder is further refined into monocrystalline silicon, a crucial component in high-tech industries, indispensable for integrated circuits and electronic elements.
4) Within metallurgy and foundry, industrial silicon powder is valued as an additive for iron base alloys and as a silicon steel alloy agent, significantly improving steel hardenability.
5) Additionally, silicon metal plays a pivotal role in the production of high-temperature materials.
