What's the melting point of ferro silicon

Nov 10, 2025

The melting point of ferrosilicon is typically between 1200°C and 1400°C, depending on the silicon content in the ferrosilicon alloy.

 

Ferrosilicon is an alloy of silicon and iron, with the silicon content usually ranging from 15% to 90%. As the silicon content increases, the melting point of ferrosilicon decreases. For example, ferrosilicon containing 75% silicon (FeSi75) has a melting point of approximately 1300°C.

 

Ferrosilicon is widely used in the steel industry as a deoxidizer and alloying additive, and its melting point characteristics are crucial for temperature control during the smelting process.
