What Are The Uses Of Ferro Silicon?

Apr 20, 2026

What are the uses of ferrosilicon?

1. In the cast iron industry, it is used as an inoculant and spheroidizing agent.

2. Ferrosilicon is added as a reducing agent when smelting certain ferroalloy products.

3. Due to silicon's important physical properties of low electrical conductivity, poor thermal conductivity, and strong magnetic permeability, ferrosilicon is also used as an alloying agent in the smelting of silicon steel.

4. Ferrosilicon is commonly used in the high-temperature smelting process of metallic magnesium in the Pidgeon process.

5. Other uses: Finely ground or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry. It can be used as a coating for welding electrodes in the electrode manufacturing industry. High-silicon ferrosilicon can be used in the chemical industry to manufacture products such as silicones.
