Metallic silicon, also known as crystalline silicon or industrial silicon, is primarily used as an additive to non-ferrous alloys. Â Metallic silicon supplier is 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 silicon is 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.
