Product Description

Product DescriptionProduct Description

The classification of metallic silicon is usually based on the content of iron, aluminum and calcium. According to the content of Fe, AL and CA in silicon metal, silicon metal can be divided into 553,441,411,421,3303,3305,2202,2502,1501,1101 and so on. In industry, metallic silicon is usually made from carbon silicon dioxide in an electric furnace. Chemical equation: Silicon from SIO2 + 2C → SI + 2CO is 97-98% pure silicon, called metallic silicon. After melting and recrystallization, 99.7 ~ 99.8% silicon metal was obtained by removing impurities with acid.

Silicon Metal is available as disc, granules, ingot, pellets, pieces, powder , rod, sputtering target, wire, and in numerous other forms and custom shapes. Ultra high purity and high purity forms also include metal powder.Name:Metallic Silicon/Silicon MetalMolecular formula: Si Molecular weight: 28.0855Specifation

UsageCertifications
Silicon is widely used in smelting ferrosilicon as alloying element in iron and steel industry and as reducing agent in many kinds of metal smelting. Silicon is also a good component in aluminum alloys, the vast majority of cast aluminum alloys contain silicon. Silicon is the raw material of ultrapure silicon in electronic industry. The electronic devices made of ultrapure semiconductor single crystal silicon have the advantages of small volume, light weight, good reliability and long life. High-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. Amorphous silicon solar cell research progress quickly, the conversion rate of more than 8% . The maximum temperature of silicon-molybdenum bar electric heating element can reach 1700 °C, it has resistance not easy to aging and good oxidation resistance. Trichlorosilane, made from silicon, can be used to make hundreds of silicone lubricants and waterproof compounds.
