Ferrosilicon is a ferroalloy with a silicon content between 15% and 90%. It is used as a source of silicon to reduce metals from their oxides and to deoxidize steel and other ferrous alloys.

Electrolytic manganese is produced through an electrolytic process, resulting in a brittle, silvery metal. It is primarily used in steel production to enhance strength, toughness, and wear resistance, and in non-ferrous alloys to improve mechanical properties and corrosion resistance.
High-purity silicon metal is a crucial raw material for industrial applications. It is used in silanes, silicones, and as an alloying agent to improve aluminum alloys' strength and corrosion resistance.
