Ferro Silicon

  FeSi

Description

Ferrosilicon is produced by reduction of silica or sand with coke in presence of scrap iron, millscale, or other source of iron.

Ferrosilicons with silicon content up to about 15% are made in blast furnaces lined with acid fire bricks. Ferrosilicons with higher silicon content are made in electric arc furnaces.

An overabundance of silica is used to prevent formation of silicon carbide. Microsilica is a useful byproduct.

The melting point and density of ferrosilicon depends on its silicon content.
