What Are The Characteristics Of Ferrosilicon?​

What Are the Characteristics of Ferrosilicon?​ 

​​Characteristic​​	​​Description​​	​​Importance​​
​​Chemical Composition​​	​​Si (15–90%), Fe (balance), traces of C, Al, Ca​​	Determines alloying strength.
​​Physical Form​​	​​Lumps, grits, or powder​​	Affects handling and application.
​​Melting Point​​	​​1200–1300°C (varies with Si content)​​	Must withstand steelmaking temps.
​​Density​​	​​~2.8–3.5 g/cm³​​	Influences mixing in molten metal.
​​Deoxidation Ability​​	​​Reacts with O₂ to form SiO₂ (slag)​​	Essential for ​​clean steel production​​.
​​Alloying Effect​​	​​Increases silicon in steel, improving hardness & corrosion resistance​​	Used in ​​HSLA, stainless, and electrical steels​​.
​​Reactivity with Water​​	​​Produces hydrogen gas (H₂)​​	Requires ​​dry storage​​.
