Ferrosilicon alloys and silicon metal have different uses

Ferrosilicon alloys, such as ferrosilicon and siliconmanganese, are commonly used as deoxidizers and alloying agents in the steel industry. They improve the physical properties of steel, such as hardness and strength, and reduce the impurity content in the final product. They are also used as inoculants to promote the formation of graphite balls in cast iron. In addition, ferrosilicon is also used as a raw material for the production of silicone resin, which is used in various industrial and consumer applications.

On the other hand, silicon metal is mainly used in the production of solar cells and semiconductor devices. It is also used as a raw material for producing organic silicon and a reducing agent for producing alloys such as aluminum and magnesium alloys. Its high purity and conductivity make it a valuable material in the electronic industry.

In summary, ferrosilicon alloys are mainly used in the steel industry, while silicon metal is used in the production of electronics, solar energy, and alloys.
