the features of silicon metal
Chemical stability: Silicon metal has good chemical stability and can be used to make ultra-pure semiconductor electronic devices, which have the advantages of small size, light weight, good reliability and long life.
Mechanical strength: silicon metal has high mechanical strength, low thermal conductivity, non-combustible, non-toxic and tasteless, can be cut, easy to transport, has the characteristics of small heat capacity, high mechanical strength, low thermal conductivity, non-combustible, non-toxic and tasteless, can be cut, and is convenient for transportation.
As an additive: Silicon metal can be used as an additive to enhance the fluidity and toughness of aluminum products. In organic chemistry, it can be used to make silicones, as well as resin and lubricant products, etc., which has high practical value.
Other properties: Silicon metal is also a good component in aluminum alloys, and the vast majority of cast aluminum alloys contain silicon. Silicon is the raw material of ultra-pure silicon in the electronics industry, and electronic devices made of ultra-pure semiconductor monocrystalline silicon have the advantages of small size, light weight, good reliability and long life. High-power transistors, rectifiers and solar cells made of silicon single crystal doped with specific trace impurities are better than those made of germanium single crystal. The maximum use temperature of the silicon-molybdenum rod electric heating element can reach 1700 °C, and it has resistance that is not easy to age and has good oxidation resistance. Trichlorosilane, produced with silicon, can be used to formulate hundreds of silicone resin lubricants and water-repellent compounds. In addition, silicon carbide can be used as an abrasive, and quartz tubes made of high-purity silicon oxide are important materials for high-purity metal smelting and lighting fixtures.
