Description
An alloy of iron and silicon used to add silicon to steel and iron, d 5.4, insoluble in water. Small quantities of silicon deoxidize the iron, and larger amounts impart special properties.
Characteristics
Ferrosilicon appears as a solid alloy of iron and silicon. Used to add silicon to iron and steel. Ferrosilicon is an odorless, crystalline solid metal. It is flammable and can react explosively with oxidizing materials. In the presence of moisture or water it may emit toxic and explosive fumes. It is used in magnesium processing.

Ferrosilicon Use and Manufacturing
Pidgeon process for producing metallic magnesium. Ferrosilicon (FeSi), which is widely used in the steel manufacturing process, is usually the source of silicon. The generated hydrogen is recycled and used in the burner to create the flame, so that the overall process is very environmentally friendly.
