Metallic silicon is the raw material for ultra-pure silicon in the electronics industry
Metallic silicon is the raw material for ultra-pure silicon in the electronics industry. Electronic devices made of ultra-pure semiconductor single crystal silicon have the advantages of small size, light weight, good reliability and long service life. High-power transistors, rectifiers and solar cells made of silicon single crystals doped with specific trace impurities are better than those made of germanium single crystals. The research on amorphous silicon solar cells has made rapid progress, and the conversion rate has reached more than 8%. The use temperature of silicon rod electric heating elements can reach 1700, and it has the characteristics of good resistance to oxidation, oxidation and oxidation. Trichlorosilane produced from silicon can be used to prepare hundreds of silicone lubricants and waterproof compounds. In addition, silicon carbide can be used as an abrasive, and quartz tubes made of high-purity silicon dioxide are important materials for high-purity metal smelting and lighting fixtures.
