Silicon Metal is an indispensable pillar of modern industries, serving as a crucial component in steel-making, cast iron, aluminum applications such as aviation, aircraft, and automobile parts production, as well as in silicon optoelectronic devices and myriad other sectors. Revered as the "salt" of modern industries, this exceptional material is forged from quartz and coke through the process of electric heating furnace smelting. With a principal silicon content of approximately 98%, the remaining composition consists of trace impurities, including iron, aluminum, and calcium, making it a reliable and high-quality industrial asset.
Crafted within the intense heat of an electric furnace, Silicon Metal lumps emerge from the transformative redox reaction between quartz and coke. The quartz surrenders its form, becoming molten silicon liquid that, once cooled, solidifies into what we know as Silicon Metal lumps. Initially massive in size, these primal lumps undergo meticulous reduction to ensure they meet industry needs.
These meticulously processed Silicon Metal Lumps are refined into the standard size range of 10-100mm, ensuring consistency and exceptional quality for versatile industrial applications.
With a captivating silver or dark grey hue and a striking metallic luster, these Silicon Metal Lumps exhibit a high melting point, exemplary heat resistance, substantial resistivity, and exceptional oxidation resistance, making them an ideal choice for demanding industrial applications.
1) Silicon Metal is an indispensable component in the world of refractory materials and power metallurgy industry, where it significantly enhances heat resistance, wear resistance, and oxidation resistance, ensuring longevity and durability.
2) Within the chemical industry, specifically in the realm of organic silicon, this industrial-grade silicon powder serves as the fundamental raw material for the production of high-performance organic silicon polymers.
3) Industrial silicon powder is transformed into monocrystalline silicon, a pivotal resource in the high-tech arena, serving as a crucial raw material for the development of integrated circuits and electronic components.
4) In the metallurgy and foundry sector, industrial silicon powder is esteemed as an iron base alloy additive and the alloying agent for silicon steel, remarkably enhancing the steel's hardenability and overall performance.
5) Silicon metal plays a vital role in the manufacturing of materials designed to withstand high temperatures, showcasing its extraordinary thermal stability and resilience.
