Metallic silicon

Metallic silicon, also known as crystalline silicon or industrial silicon, is primarily used as an additive to non-ferrous alloys.Metallic silicon supplieris the product that is smelted by quartz and coke in electric heating furnace, the content of element of main component silicon is in about 98% (contain Si content 99.99% also contain in metallic silicon), other impurity is iron, aluminium, calcium to wait..According to statistics, in 1985 the world consumed about 500,000 tons of silicon metal, of which about 60% was used for aluminum alloy, less than 30% for organic silicon, about 3% for semiconductor, and the rest for steel smelting and precision ceramics.

Use of the silicon matal

Silicon is widely used in smelting ferrosilicon alloy as alloying element in steel industry and as reducing agent in many kinds of metal smelting.Silicon is still a good component in aluminum alloys, most of which contain silicon.Metallic siliconis the raw material of ultrapure silicon in electronic industry. The electronic devices made of ultrapure semiconductor monocrystalline silicon have the advantages of small size, light weight, good reliability and long life.Silicon carbide can be used as abrasive, quartz tube made of high purity silicon oxide is an important material for high purity metal smelting and lighting.It has the characteristics of small heat capacity, high mechanical strength, low thermal conductivity, non-combustion, non-toxic and tasteless, cutting, convenient transportation and so on. It can be widely used in metallurgy, electric power, chemical industry, ships and other thermal equipment and pipelines.

History

Belongs to energy-intensive manufacturing silicon metal smelting, silicon metal production in our country already has a long history, along with the national energy policy tightening and the development of energy conservation and emissions reduction, and to the promotion of the new energy, has become the primary silicon metal smelting products and processes, a lot of domestic new energy enterprises construction metal silicon, polycrystalline silicon, monocrystalline silicon, solar cells and so on a series of circulation industry chain, in the next few years is bound to affect the whole development of our energy and new energy should be.

crystalline siliconSituation

From 2012 to 2017, China's exports of metallic silicon showed a fluctuating trend.Among them, the export volume of metal and silicon increased as a whole in 2017 compared with the previous year, reaching 83794.83 tons in 2017, up 17.24% compared with the previous year, with a larger increase.
