Ferro Silicon uses coke, silicon as raw materialand is made by electric furnace. Because silicon and oxygen are easily compound into SiO2, the Ferrosilicon is often used as deoxidizer in steelmaking. It also can be used as a suspended phase in the mineral processing industry and coatings for welding electrodes in the electrode manufacturing. According to the content of silicon, this product can be divided into FeSi with the Si content 75%, 72%, 65%, 60%, 45%.
