The specific gravity of ferrosilicon

What is the specific gravity of ferrosilicon?

The specific gravity of ferrosilicon varies with the silicon content. Generally, the specific gravity of ferrosilicon is about 4.75 g/cm3. As the silicon content increases, the specific gravity of ferrosilicon will gradually decrease. For example:

Ferosilicon with a silicon content of 40% to 47% has a specific gravity of about 5.61 to 5.15 g/cm3.
Ferosilicon with a silicon content of 72% to 80% has a specific gravity of about 3.27 to 3.03 g/cm3.
Ferosilicon with a silicon content of 87% to 95% has a specific gravity of about 2.78 to 2.50 g/cm3.

In addition, the density (i.e. specific gravity) of ferrosilicon may also be affected by factors such as impurity composition and production process.
