Ferrosilicon
Ferrosilicium is an alloy of iron and silicon with a minimum silicon content of 8.0% and a maximum of 95.0%, obtained by reduction of oxide materials or by fusion of components.
Ferrosilicon is used in the metallurgical industry for deoxidization and alloying of steel, alloys, modification of cast iron and in the processes of obtaining ferroalloys, as well as in other branches of the metallurgical industry.
