Industrialsilicon refers to the silicon powder content isgreater than or equal to 98.5% pure silicon products. Industrial silicon as anon ferrous alloy additives. Industrial silicon is also used in demandingsilicon steel alloy agent, smelting special steel and non ferrous alloydeoxidizer. Industrial silicon through a series of processing, Korah made ofsilicon, for the electronics industry use, in the chemical industry for theproduction of organic silicon, so it has magic metal called, its use is veryextensive.

Industrial silicon add to aluminum, ironand other metal, can be improved or enhanced metal performance. Car ( includingmotorcycle ) with aluminum to silicon of the considerable demand, so a region,country of auto industry development to industrial silicon market decline hasdirect influence.

Industrial silicon is further purified to99.999% above, make polycrystalline silicon ( cylinder ), and then mechanicalcutting into monocrystalline silicon, applied to the large number of electronicinformation industry. For example, all types of IC card, VCD film, DVD film.

Ferrosilicon, ferrosilicon is used coke,steel scrap, quartz ( or silica ) as raw material, using the submerged arcfurnace smelting. Silicon and oxygen easily synthesis of silica. So theferrosilicon often used for steelmaking deoxidizer, at the same time as theSiO2 generation release a lot of heat, while deoxidizing, improve thetemperature of molten steel is also advantageous. Ferrosilicon as alloyadditives. Widely used in low alloy structural steel, alloy structural steel,spring steel, bearing steel, heat-resistant steel and electrical silicon steel,silicon in ferroalloy production and in the chemical industry, used as reducingagent. Silicon amounted to 95%-99%. Pure silicon used in manufacturingmonocrystalline silicon or preparation of non-ferrous metal alloys.

Ferrosilicon in steel industry, foundryindustry and other industrial production is widely used. Silicon iron is an essentialdeoxidizer in the steel industry. In steelmaking, ferrosilicon is used toprecipitate deoxidization and diffusion deoxidation. dth hammer Adobe iron also asalloying agent for steelmaking. According to metal powder supplier, add acertain amount of silicon in steel, can significantly increase the strength ofsteel, hardness and elasticity, improve steel permeability, reduce transformersteel hysteresis loss. General steel containing silicon in 0.15%-0.35%,structural steel containing silicon in 0.40%^ 1.75%, tool steel containing silicon in 0.30%^ 1.80%, spring steel containingsilicon in 0.40%^ 2.80%,stainless steel containing silicon in 3.40%^ 4%, heat-resistant steel containing silicon in 1%^ 3%, silicon steel containingsilicon in 2% ^3% or higher.In the steel industry, produce a ton of steel consumes about 3^ 5kg75% ferrosilicon.

High silicon ferrosilicon and silicon alloyin ferroalloy industry used in producing low carbon iron alloy, reducing agent.Ferrosilicon joined the cast iron can be used for rock drill bits ductile cast iron inoculant,and can prevent the formation of carbides, promoting graphite precipitation andspheroidizing, improve the properties of cast iron. In addition, silicon powderin the mineral processing industry can be used for suspending phase, themanufacturing industry for welding rod coating; high silicon ferrosilicon inelectrical industry can be used for preparing semiconductor silicon, in thechemical industry can be used for manufacturing silicone etc.
