Ferrosilicon is a ferroalloy - an alloy of iron and silicon. The average silicon content varies between 15 and 90 wt%. It contains a high proportion of iron silicides. Ferrosilicon is produced by reduction of silica or sand with coke in presence of iron.

The following are the common application areas of ferrosilicon:

  • As a source of silicon to reduce metals from their oxides and to deoxidize steel and other ferrous alloys.
  • Manufacture of other ferroalloys
  • Manufacture of silicon, corrosion-resistant and high-temperature resistant ferrous silicon alloys, and silicon steel for electromotors and transformer cores
  • Manufacture of cast iron, ferrosilicon is used for inoculation of the iron to accelerate graphitization.
  • Manufacture of prealloys like magnesium ferrosilicon, used for modification of melted malleable iron.
  • As an additive to cast irons for controlling the initial content of silicon
  • In steel melting, casting, mineral processing and melting rod industry
  • Used in the Pidgeon process to make magnesium from dolomite
  • For heavy media separation and atomization
  • Used in casting, melting and related metallurgy industry
  • For production of semiconductor pure silicon in electric industry and silicon copper in chemistry industry. Specification of ferro silicon use in steel industry :
