Product Description
Metallic silicon, also known as crystalline silicon or industrial silicon, its main use is as a non-iron-based alloy additives. Silicon metal is produced by smelting quartz and coke in electric furnaces. The main component, silicon, is around 98% (in recent years, 99.99% of silicon is also contained in silicon metal) , the other impurities are iron, aluminum, calcium and so on.
Silicon is widely used in smelting to produce ferrosilicon alloys as alloying elements in the steel industry, and as a reducing agent in many metal smelting processes. Silicon is still a good component in aluminum alloys, and the vast majority of cast aluminum alloys contain silicon. Silicon is the raw material for ultra pure silicon in the electronics industry. Electronic devices made from ultra pure semiconductor single crystal silicon have advantages such as small size, light weight, good reliability, and long lifespan. High power transistors, rectifiers, and solar cells made from silicon single crystals doped with specific trace impurities are better than those made from germanium single crystals. The research progress of amorphous silicon solar cells is very fast, with a conversion rate of over 8%. The maximum operating temperature of silicon molybdenum rod electric heating elements can reach 1700 ºC, with resistance that is not easily aged and good oxidation resistance. Trichlorosilane produced from silicon can be formulated with hundreds of silicone resin lubricants and waterproof 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. Paper of the 1980s - Silicon is referred to as "paper of the 1980s" by people. This is because paper can only record information, while silicon can not only record information, but also process it to obtain new information. The world's first electronic computer, manufactured in 1945, was equipped with 18000 tubes, 70000 resistors, and 10000 capacitors. The entire machine weighed 30 tons and covered an area of 170 square meters, equivalent to the size of 10 rooms. Today's electronic computers, due to technological advancements and material improvements, can accommodate tens of thousands of transistors on a silicon wafer the size of a fingernail; And it has a series of functions such as input, output, operation, storage, and control information. Micro porous silicon calcium insulation material is an excellent insulation material. It has the characteristics of small thermal capacity, high mechanical strength, low thermal conductivity, non combustion, non-toxic and tasteless, cuttable, convenient transportation, etc. It can be widely used in various thermal equipment and pipelines such as metallurgy, electric power, chemical industry, ships, etc. After testing, the energy-saving benefits are superior to insulation materials such as asbestos, cement, vermiculite, and cement perlite. Special silicon calcium materials can be used as catalyst carriers and are widely applied in various fields such as petroleum refining and automobile exhaust purification.
