| Ferrosilicon is primarily used as a deoxidizing and alloying agent in the steel manufacturing process. |
| In the second process, the ore is converted to magnesium oxide, which is then treated with the alloy ferrosilicon. |
| Microsilica or silica fume is a by-product in the manufacture of silicon and ferrosilicon alloys. |
| One of the most common silicon-iron alloys, for example, is ferrosilicon. |
| Late additions of ferrosilicon have been reported to increase toughness. |
