Silicon Metal is an indispensable element for modern industry, revered for its versatility and essential role across numerous sectors. Its applications extend across steel-making, cast iron, aluminum production for aviation, aircraft, and automotive components, as well as silicon optoelectronic devices, among others. Often referred to as the 'salt' of modern industries, Silicon Metal is derived from the smelting of quartz and coke within an electric heating furnace. Boasting a silicon content of approximately 98%, this remarkable material is complemented by minimal impurities such as iron, aluminum, and calcium, making it a vital component in advanced industrial processes.
The production of Silicon Metal lumps is a fascinating process involving the transformation of quartz and coke in an electric heating furnace. The redox reaction converts quartz into a molten silicon liquid, which, upon cooling, solidifies into the large primal silicon metal lumps we recognize. These massive lumps are then carefully processed to
become the smaller, standardized Silicon Metal lumps that measure between 10-100mm, perfect for diverse industrial applications.
Characterized by its silver-gray or dark-gray appearance and distinctive metallic luster, Silicon Metal exhibits a high melting point, excellent heat resistance, and formidable oxidation resistance. Its high resistivity further underscores its superiority in demanding applications, making it an invaluable asset in the realm of high-performance materials.
1) Silicon Metal is extensively utilized in the refractory material and power metallurgy sectors to significantly enhance heat resistance, wear resistance, and oxidation resistance. This makes it an indispensable asset for industries seeking to improve durability and efficiency in their operations.
2) In the realm of organic silicon chemistry, industrial silicon powder serves as the fundamental raw material necessary for the production of high polymers. This application underscores its role as a cornerstone in the creation of innovative silicon-based products.
3) Industrial silicon powder undergoes sublimation into monocrystalline silicon, a critical component in the high-tech arena. It is an essential raw material employed in the manufacturing of integrated circuits and electronic elements, contributing to the advancement of modern technology.
4) Within the metallurgy and foundry industries, industrial silicon powder is esteemed as an iron base alloy additive and a crucial element in the production of silicon steel. Its inclusion enhances the hardenability and performance of steel, leading to superior quality and strength.
5) Silicon metal is instrumental in the creation of high-temperature materials, offering unmatched resilience and reliability for applications that demand exceptional thermal performance.
