Silicon Metal stands as a pivotal industrial cornerstone, instrumental in a wide array of sectors including steel-making, cast iron, and aluminum manufacturing, essential for aviation, aircraft, and automobile production. Additionally, it plays a crucial role in the realm of silicon optoelectronic devices as well as numerous other industries, earning its reputation as the "salt" of modern industry. This remarkable metal is crafted from quartz and coke through the advanced process of electric heating furnace smelting, boasting an impressive silicon content of approximately 98%. The remaining composition includes minor impurities such as iron, aluminum, and calcium, making it an indispensable material across various applications.
The production of Silicon Metal Lump involves a sophisticated process within an electric heating furnace, utilizing quartz and coke. In this process, quartz undergoes a redox reaction, transforming into molten silicon liquid. Following a careful cooling process, it solidifies into the substantial silicon metal lump we recognize. Initially, these lumps are quite large, demonstrating their raw form and potential before further refinement.
These large primal silicon metal lumps are subsequently refined into smaller, standardized sizes, resulting in Silicon Metal Lumps ranging from 10-100mm, perfectly suited for a multitude of industrial applications.
Characterized by its silver-gray or dark gray hue with a captivating metallic luster, Silicon Metal boasts a high melting point, exceptional heat resistance, impressive resistivity, and unparalleled oxidation resistance, making it a superior choice for advanced industrial use.
1) Silicon Metal is extensively utilized within the refractory material and power metallurgy sectors. It is renowned for its ability to significantly enhance heat resistance, wear resistance, and oxidation resistance, making it indispensable in these demanding industries.
2) Within the realm of organic silicon chemistry, industrial silicon powder serves as the foundational raw material for the creation of high-performance organic silicon polymers, which are critical in various advanced applications.
