Chemical composition table of common metallic silicon

Introduction to Silicon Metal

Industrial silicon, also known as silicon metal crystalline silicon, is obtained by reducing silicon dioxide with a carbonaceous reductant in a mineral furnace, and is an important raw material for the production of silicone, polysilicon and aluminium alloys. Industrial silicon is produced from silicon dioxide, carbonaceous reductant and relaxing agent as raw materials through continuous electrothermal chemical reaction in mineral furnace. In the smelting production process, the material required for production is firstly sent to the silo in the ore furnace workshop by the raw material handling system, then, according to the specific gravity of the material, it is transported by the conveying equipment to the top silo or the storage silo on the operating platform in the ore furnace workshop, and the charge is added to the furnace by the furnace operator.

Introduction to Common Silicon Metal

Silicon metal smelting belongs to the high energy consumption production, China's silicon metal production has been a long time, with the tightening of the national energy policy and energy saving and emission reduction, as well as the promotion of new energy sources, silicon metal smelting has become the primary products and processes, many domestic emerging energy companies to build a series of silicon metal, polysilicon, monocrystalline silicon, solar cells and other recycling industrial chain, the next few years will inevitably affect the development of the entire energy sector and new energy sources in China. The next few years will inevitably affect the development of China's entire energy sector and the application of new energy.

Uses of Common Silicon Metal

Silicon is used in large quantities for smelting into ferrosilicon alloys as an alloying element in the iron and steel industry, and as a reducing agent in the smelting of many kinds of metals. Silicon is also a good component in aluminium alloys, and most cast aluminium alloys contain silicon. Silicon is the raw material of ultra-pure silicon for the electronics industry, ultra-pure semiconductor monocrystalline silicon made of electronic devices with small size, light weight, good reliability and long life and other advantages. Doped with specific trace impurities of silicon monocrystal made of high-power transistors, rectifiers and solar cells, than made of germanium monocrystal. Amorphous silicon solar cell research is progressing rapidly, the conversion rate reached more than 8 per cent. Silicon molybdenum rod electric heating element maximum operating temperature of up to 1700 ℃, with resistance is not easy to aging and good antioxidant properties. Silicon production of trichlorohydrosilicon, can be formulated with hundreds of silicone resin lubricants and waterproof compounds.
