1. Metallurgical industry
Ferrosilicon is one of the indispensable raw materials in steel smelting. It can be used to reduce impurities in molten iron and increase the corrosion resistance of steel bars. In addition, ferrosilicon can also be used as a casting alloy to improve the hardness, tensile strength and corrosion resistance of castings.

2. Electronic industry
Ferrosilicon is also an important raw material for manufacturing semiconductors and other electronic components. In the semiconductor production process, ferrosilicon can be used to make monocrystalline silicon or polycrystalline silicon to make solar panels, integrated circuits, transistors, etc.

3.Chemical industry
Ferrosilicon is also used in the production of chemicals such as fertilizers and pesticides. The silicon in ferrosilicon can be used to make organosilicon compounds such as silanol and silanes, which can be used to make lubricants, coatings, adhesives, etc.
