Metallic silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Metallic silicon is a product made of quartz and coke smelted in an electric furnace. The content of the main component silicon is about 98%, and the other impurities are iron, aluminum, calcium, etc. In industry, silicon metal is usually produced by reducing silicon dioxide by carbon in an electric furnace. Chemical reaction equation: the purity of silicon prepared by SiO2+2C Si+2CO is 97 98%, which is called metallic silicon. Then it is melted and recrystallized, and impurities are removed with acid to obtain metallic silicon with purity of 99.7~99.8%. Metal silicon particles: 1-200mm silicon metal should be used to produce organic silicon, produce high-purity semiconductor materials and prepare alloys with special purposes. (1) Production of silicone rubber, silicone resin, silicone oil and other silicone. (2) Manufacture high-purity semiconductors. (3) Prepare alloy.
