Ferro-silicon
FeSi
Introduction:
Ferrosilicon, or ferrosilicium, is an alloy of iron and silicon with between 15 and 90% silicon. It contains a high
proportion of iron silicides. It also contains about 1 to 2% of calcium and aluminum.Of course, it can be used
by end users (steel plants, foundries…) as inoculant, but it is also used in the process to create other ferro
alloys (such as FeSiMg) and magnesium.
China is the largest producer of ferrosilicon in the world.
