Ferrosilicon is an iron-silicon alloy made from coke, steel scraps, quartz (or silica) as raw materials and smelted in an electric furnace. Since silicon and oxygen easily combine to form silica, ferrosilicon is often used as a deoxidizer in steelmaking. At the same time, since SiO2 releases a large amount of heat when it is generated, it is also beneficial to increase the temperature of molten steel while deoxidizing.

Ferrosilicon is an essential deoxidizer in the steelmaking industry. In torch steel, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steelmaking. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of the steel, increase the magnetic permeability of the steel, and reduce the hysteresis loss of transformer steel.

High-silicon ferrosilicon or siliceous alloys are used in the ferroalloy industry as reducing agents for the production of low-carbon ferroalloys. Ferrosilicon can be used as an inoculant for ductile iron when added to cast iron, and can prevent the formation of carbides, promote the precipitation and spheroidization of graphite, and improve the performance of cast iron.

In addition, ferrosilicon powder can be used as a suspended phase in the mineral processing industry and as a coating for welding rods in the welding rod manufacturing industry; high-silicon ferrosilicon can be used in the electrical industry to prepare semiconductor pure silicon and in the chemical industry to manufacture silicone, etc.
