The purpose of the Metal silicon

Into silicon used for smelting ferrosilicon alloy as alloying elements in steel industry, as a reducing agent in many kinds of metal smelting. Silicon or aluminum alloy good group in yuan, the vast majority of casting aluminium alloy containing silicon. Silicon is a raw material for electronic industry ultrapure silicon ultra pure monocrystalline silicon semiconductor electron device has small volume, light weight, good reliability and long service life, etc. Mixed with a certain number of trace impurities of high-power transistor, rectifier and solar cells, and is better than made of single crystal germanium. Amorphous silicon solar cell research progress quickly, conversion rate reached more than 8%. Silicon molybdenum rods highest use electric heating element temperature can reach 1700 ℃, has good resistance to aging and oxidation resistance. Chemical hydrogen silicon with silicon production, can make hundreds of silicone lubricants and waterproofing compound, etc. In addition, the silicon carbide can be abrasive, high purity silica quartz tube is made of high purity metal smelting and lighting lamps and lanterns is the important material. Paper in the eighty s - silicon people call for the "paper" in the eighty s. This is because the paper can only record information, and silicon can not only record information, also can carry on the processing of information processing in order to obtain new information. The world's first electronic computer made in 1945, with 18000 vacuum tubes, 70000 70000 resistor, capacitor, the whole machine weighed 30 tons, covers an area of 170 square meters, equivalent to 10 house size. Today the electronic computer, due to advances in technology and the improvement of the material, on a fingernail silicon wafers, can accommodate tens of thousands of transistors; And there are input, output, a series of functions such as computing, storage, and control information. Porous silicon calcium thermal insulation material microporous calcium silicon thermal insulation material is a kind of excellent thermal insulation material. It has small heat capacity, high mechanical strength, low thermal conductivity, noncombustible, non-toxic, tasteless, can be cut, transportation is convenient wait for a characteristic, can be widely used in metallurgy, electric power, chemical industry, ship, etc all kinds of thermal equipment and pipe. After the test, the energy saving efficiency is better than that of asbestos and cement, cement perlite and vermiculite insulation materials. Special silicon calcium materials can be used as a catalyst carrier, such as oil refining, automobile exhaust purification is widely used in many aspects.
