Also called silicon metal silicon or silicon, is mainly used as the additive non ferrous alloy. Silicon metal is composed of quartz and coke in the electric furnace smelting products, the principal component of silicon content is about 98% (in recent years, the content of Si of 99.99% is also included in the inside, the remaining impurities in silicon metal) for iron, aluminum, calcium etc..

Silicon is widely used in smelting ferrosilicon alloys as alloying elements in the steel industry and as a reducing agent in many kinds of metal smelting. Silicon is also a good component in aluminium alloys, and most cast aluminum alloys contain silicon. Silicon is the raw material of the ultra pure silicon in the electronics industry, and the electronic devices made of ultra pure semiconductor monocrystalline silicon have the advantages of small size, light weight, good reliability and long service life. Large 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, and the conversion rate has reached over 8%. The maximum service temperature of the silicon molybdenum rod electric heating element can reach 1700 DEG C, and has the advantages of resistance, aging resistance and good oxidation resistance. With the production of silicon trichlorosilane, can be made of hundreds of silicone lubricant and waterproof compound etc.. In addition, silicon carbide can be used as abrasive and high-purity silicon oxide tube is an important material for high purity metal smelting and lighting fixtures. 80s paper - silicon, known as "80s paper"". This is because the paper can only record information, and silicon can not only record information, but also the processing of information processing, in order to obtain new information. In 1945, the world's first electronic computer, equipped with 18000 electronic tubes, 70000 resistors, 10000 capacitors, the whole machine weighs 30 tons, covers an area of 170 square meters, equivalent to 10 house size. The computer today, due to advances in technology and material improvement in silicon chip the size of a fingernail, can accommodate tens of thousands of transistors; and the input and output, computing, storage and control information and a series of functions. Microporous calcium silicate insulation material, microporous calcium silicate insulation material, is a kind of excellent thermal insulation material. It has the characteristics of small heat capacity, high mechanical strength, low thermal conductivity, non flammable, non-toxic and tasteless, can be cut, the transportation is convenient, and can be widely used in metallurgy, electric power, chemical industry, shipbuilding and other thermal equipment and pipe. It has been proved that energy saving is superior to asbestos, cement, vermiculite and cement perlite. Special calcium silicate material can be used as catalyst carrier, widely used in petroleum refining, automobile exhaust purification and so on.
