Use Of Silicon

- Jul 24, 2018 -

Silicon alloys are used in large quantities as alloying elements in the iron and steel industry and as reductant in many kinds of metal smelting. Silicon is also a good element in aluminum alloy, most of the cast aluminum alloy contains silicon. Silicon is the electronic industry ultra pure silicon raw material, the Ultra pure semiconductor monocrystalline silicon makes the electronic device to have the small size, the light weight, the reliability is good and the life long and so on the advantage. High-power transistors, rectifiers and solar cells, made of silicon crystals with specific trace impurities, are better than those made from germanium crystals. The research progress of amorphous silicon solar cells is very fast, and the conversion rate reaches over 8%. The maximum temperature of the silicon-molybdenum rod electrothermal element is up to 1700 ℃, which is not easy to be aged and has good antioxidant properties. The production of hundreds of kinds of silicone lubricants and waterproof compounds can be made from silicon-producing tri-chloro-silicon. In addition, SIC can be used as abrasive, high-purity silica made of quartz tube is a high purity metal smelting and lighting important materials. The 80 's paper-silicon people called silicon "the paper of the 80 's." This is because the paper can only record information, and silicon not only records information, but also processing information processing to obtain new information. The world's first computer, made in 1945, contains 18,000 tubes, 70,000 resistors, 10,000 capacitors, and the entire machine weighs 30 tonnes, covering an area of 170 square meters, equivalent to 10 house sizes. Today's electronic computers, thanks to advances in technology and improved materials, can hold tens of thousands of transistors on a fingernails sized wafer and have a range of functions such as input, output, operation, storage, and control information. Micro-porous silicon calcium insulation material microporous silicon calcium insulation material is an excellent insulation material. It has a small thermal capacity, high mechanical strength, low thermal conductivity, not burning, non-toxic tasteless, can be cut, convenient transportation and other characteristics, can be widely used in metallurgy, electricity, chemical, shipbuilding and other thermal equipment and pipelines. After testing, energy-saving benefits than asbestos, cement, vermiculite and cement perlite and other insulation materials. Special silicon-calcium material can be used as catalyst carrier in petroleum refining, automobile exhaust purification and so on.
