Ferrosilicon in steel mills and casting as the source of silicon is used. Also in plain carbon steel, low alloy and high-alloy deoxygenation to use in the production of Ferro Alloys silico method of thermite is used. Silicon role of alloying element in steel production in nuclear electrical transformers and electro is used. Ferrosilicon as a supplier of silicon to gray and ductile iron casting rate of 3% is used. The material forming the base Ferrosilicon analysis ferrosilico cast magnesium and modifiers. As part of the wire coating composition (flower pots) in some welding electrodes used.


The American Concrete Institute (ACI) defines Microsilica as “very fine non-crystalline silica produced in electric arc furnaces as a by-product of production of elemental silicon or alloys containing silicon” (ACI 116R). It is different from pulverized silica. Microsilica, also known as silica fume.
