Metallic silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for nonferrous alloys. Silicon metal is a product made by smelting quartz and coke in an electric furnace. The main component silicon element content is about 98% (in recent years, 99.99% of silicon content is also included in silicon metal), and the rest impurities are iron, aluminum, calcium, etc.
purpose
Silicon is widely used in smelting ferrosilicon alloy as alloy element in iron and steel industry, and as reducing agent in many kinds of metal smelting. Silicon is also a good component in aluminum alloy. Most of the cast aluminum alloy contains silicon. Silicon is the raw material of ultrapure silicon in electronic industry. The electronic devices made of ultrapure semiconductor single crystal silicon have the advantages of small volume, light weight, good reliability and long service life. High power transistors, rectifiers and solar cells made of single crystal silicon doped with specific trace impurities are better than those made of single crystal germanium. The research progress of amorphous silicon solar cells is very fast, and the conversion rate is over 8%. The maximum operating temperature of the silicon molybdenum bar electric heating element can reach 1700 ℃, which has the properties of resistance aging and good oxidation resistance. Trichlorosilane produced with silicon can be used to prepare hundreds of silicone lubricants and waterproof compounds. In addition, silicon carbide can be used as abrasive. The quartz tube made of high-purity silicon oxide is an important material for high-purity metal smelting and lighting lamps Paper in the 1980s - silicon people call silicon "paper in the 1980s.". This is because paper can only record information, while silicon can not only record information, but also process information to obtain new information. The world's first electronic computer, manufactured in 1945, is equipped with 18000 electronic tubes, 70000 resistors and 10000 capacitors. The w |
