Silicon Metal stands as an indispensable industrial marvel, seamlessly woven into the fabric of modern manufacturing. This vital component finds its place in steel-making, cast iron production, aluminum crafting for aviation, aerospace, and automotive sectors, and even in the dynamic realm of silicon optoelectronic devices, among many other applications. Revered as the 'salt' of contemporary industries, metal silicon emerges from a meticulous smelting process involving quartz and coke within electric heating furnaces. The silicon's core composition is an impressive 98% purity, with trace impurities consisting of iron, aluminum, and calcium, ensuring optimal performance and reliability.
The crafting of Silicon Metal lumps is a fascinating journey of transformation. Born within the intense heat of electric heating furnaces, quartz and coke undergo a remarkable redox process, giving rise to the molten silicon liquid. Once cooled, this liquid solidifies into the substantial primal silicon metal lumps we recognize. Initially formidable in size, these lumps are then expertly crafted
into more manageable entities, aptly termed standard size, with dimensions ranging from 10-100mm. This meticulous sizing process ensures ease of use and integration into various industrial applications.
Boasting a captivating silver gray or dark gray hue, Silicon Metal is characterized by its distinct metallic luster.
