Silicon single crystal doped with specific traceimpurities made of high-power transistors

It has a small heatcapacity, high mechanical strength, low thermal conductivity, non-burning,non-toxic, tasteless, can be cut, easy to transport, and can be widely used inmetallurgy, electric power, chemicals, shipbuilding and other thermal equipmentand piping.Silicon aluminum alloy is the largestamount of silicon alloy. Additional products include microsilica, siliconedge leather, black silicon, silicon metal slag.Silicon metal is the industrial purification elemental silicon, is mainly used for the production of organic silicon, prepare high purity semiconductor materials as well as the preparation of special purpose alloys.80; thedensity is 2.Silicon-copper alloy has good weldability, is not easy to produce sparks,explosion-proof function when impacting, can be used for producingtanks. Silicone rubber with goodelasticity, high temperature resistance, for the production of medicalsupplies, fire-resistant gasket, silicon resin used in the production ofinsulating paint, high temperature coatings and so on. The micropore CaSiinsulation material is an excellent insulation material. Thesilicon aluminum density, low coefficient of thermal expansion, good castingproperties and resistance to wear, the fight against high impact capacity andgood high pressure dense, can greatly improve the life of the spacecraft,commonly used in its production with a cast alloy castings and auto parts.

 

Which the microsilica, alsoknown as silica fume or silicon powder, and it iswidely used in refractory and concrete industry.com.Addingthe silicon steel plates made ofsilicon in steel can greatly improve the steel magneticpermeability to reduce the hysteresis and eddy current losses, available itsmanufacture the iron core of transformers and motors, to Flocked swabs manufacturing equipment Factory improve theperformance of the transformer and motor.After the test, its energy-saving benefits is superior to asbestos,cement, vermiculite, cement perlite and other insulation materials. Amorphous silicon solar cell research in recent years progress,the conversion rate is more than 8%.The extensive application of the metallic silicon.According to metal powder supplier, silicon is a nonmetallic element, gray, metallic color, hard and brittle.The silicone oil is an oil, the viscosityis little affected by the temperature, used to produce advanced lubricants,polishing agents, fluid spring, the dielectric liquid and so on, also can beprocessed into a colorless and transparent liquid, spraying as advancedwaterproofing agent in the building surface. The silicon content is account for about 26% in the earthcrust; atomic weight is 28.mhcmp.The production of silicone, siliconerubber, silicone resin, silicone oil and so on.m.The manufacture of high-puritysemiconductor, modern, large-scale integrated circuits are almost made ofhigh-purity silicon metal, and the high purity silicon metal also the main rawmaterial of the optical fiber, it can be said that silicon metal has become apillar industry of the basis of the information age.

Silicon single crystal doped with specific traceimpurities made of high-power transistors, rectifiersand solar cells is better than germanium crystal.The siliconmetal is made of quartz and coke in an electricfurnace smelting into product, the main component silicon element content ofaround 98%, the remaining impurities such as iron, aluminum, calcium.Silicon is the raw material of ultra-puresilicon electronics industry, the devices made of ultrapure semiconductorsilicon electronic with the advantages of small size, light weight, goodreliability and long life. Silicon molybdenum rod heatingelement maximum use temperature up to 1700 ,the resistance is not easy to aging and good oxidation.melting point is 1410C;boiling point is 2355C;resistivity is 2140.The silicon-aluminum alloy is a strong composite deoxidizerin the steelmaking process instead of pure aluminum can improve the utilizationof a deoxidizer, and purify the liquid steel, improve the quality of steel. Silicon resources is refer to crystal, quartz veins,quartz gravel (gravel quartz), natural silica sand and so on, is a non-metallicmineral, the main chemical ingredient is SiO2, rich in nature.
