Silicon Metal is an indispensable industrial powerhouse, essential for a range of applications including steel-making, cast iron production, and the fabrication of aluminum components used in aviation, aircraft, and automobiles. Moreover, its presence is vital in the realm of silicon optoelectronic devices and a plethora of other industries. Often lauded as the "salt" of modern industries, Metal silicon is meticulously crafted by smelting quartz and coke in an electric heating furnace. The primary component, silicon, boasts a remarkable purity with a content close to 98%, accompanied by minor impurities such as iron, aluminum, and calcium.
Silicon Metal lumps are expertly produced using state-of-the-art electric heating furnaces where quartz and coke undergo a redox reaction, transforming into molten silicon liquid. Following a meticulous cooling process, this liquid solidifies into the large primal silicon metal lumps that we recognize. These sizeable forms are subsequently
processed into more manageable, standardized chunks. Recognized as Silicon Metal Lumps, these are refined into practical sizes ranging from 10-100mm, perfect for various industrial applications.
Exhibiting a striking silver gray or deep dark gray hue, these lumps glisten with a metallic sheen. They are renowned for their high melting point, exceptional heat resistance, impressive resistivity, and outstanding oxidation resistance, making them a preferred choice for demanding industrial processes.
1) Silicon Metal is extensively utilized in the refractory material and power metallurgy industries, where it significantly enhances heat resistance, wear resistance, and oxidation resistance, making it indispensable.
2) In the chemical realm of organic silicon, industrial silicon powder serves as the foundational raw material necessary for the formation of high polymers in organic silicon products, driving innovation and development.
3) Industrial silicon powder is transformed into monocrystalline silicon-a pivotal substance in the high-tech sector, essential for crafting integrated circuits and electronic components.
4) Within the metallurgy and foundry sectors, industrial silicon powder is esteemed as a vital iron base alloy additive and a crucial pharmaceutical in silicon steel production, thereby enhancing the steel's hardenability and performance.
5) Silicon metal plays a critical role in the production of high-temperature materials, ensuring resilience and durability under extreme conditions.
