Production of siliconmetal

raw materials:

Carbon electrodes play a main role in theproduction processes in submerged are furnaces. Carbon electrodesare most largely used for the production of silicon metal. Theprocess consists in the continuous reduction of quartz(SiO2) into silicon by a reducing mixture according tothe simplified relation SiO2 2C → Si2CO.

Application

1. When silicon is purified and doped with suchelements as boron, phosphorus and arsenic, it is used as asemiconductor in various applications. For maximum purity, achemical process is used that reduces silicon tetrachloride ortrichlorosilane to silicon.

2. Silicon oflower purity is used in metallurgy as a reducing agent and as analloying element in steel, brass, aluminium, and bronze. When smallamounts of silicon are added to aluminum, aluminum becomes easierto cast and also has improved strength, hardness, and otherproperties.

3. Siliconmetal can be grinded into silicon powder in variousapplications.

4. Siliconmetal is also the base material for making silicones used in suchproducts as synthetic oils, caulks and sealers, and anti-foamingagents.
