, commonly abbreviated FeSi, is produced by the reduction of silica or sand with coke in the presence of iron. Typical sources of iron are scrap iron or mill scale. Ferrosilicons with silicon content up to about 15% are made in blast furnaces lined with acid-fired bricks.

Ferrosilicon is also used for the manufacture of silicon, corrosion-resistant and high-temperature-resistant ferrous silicon alloys, and silicon steel for electromotors and transformer cores. In the manufacture of cast iron, ferrosilicon is used for inoculation of the iron to accelerate graphitization. In arc welding, ferrosilicon can be found in some electrode coatings.
