Manganese and silicon are crucial constituents in steelmaking, as deoxidants, desulphurizers and alloying elements. Silicon is the primary deoxidizer. Manganese is a milder deoxidizer than silicon but enhances the effectiveness due to the formation of stable manganese silicates and aluminates. It also serves as desulphurizer.
