ferrosilicon

Ferrosilicon is an alloy composed of iron and silicon, typically containing 15% to 95% silicon. It is a type of ferroalloy, which are alloys of iron with other metals used to introduce specific elements into steel production.12

Ferrosilicon is primarily used to remove oxygen from molten steel, a process known as deoxidizing. It is also used in the creation of silicon steel and high-silicon cast iron. Ferroalloys like ferrosilicon have lower melting points than pure metals, allowing them to be easily incorporated into molten steel to achieve desired chemical compositions and properties for various steel products. The production of ferroalloys generally involves heating ores, iron, and coke in electric furnaces.12
