Metallic silicon is a high-purity form of silicon, typically containing between 98% and 99%. It is primarily used in the production of various alloys, with significant applications in steel, aluminum alloys, and electronic products. The production process of metallic silicon generally involves extracting it by reacting silicon sand (such as quartz) with a carbon source (such as coke) at high temperatures. In the electronics industry, metallic silicon is a key raw material for manufacturing semiconductors and solar cells. Additionally, metallic silicon is used in the production of steel and aluminum alloys, where it enhances the strength and corrosion resistance of the alloys.
