Zirconium is one of the most reactive elements that forms stable compounds with oxygen, nitrogen, sulphur and carbon. It is also used as a de-oxidant to modify non-metallic inclusions and also fixes uncombined nitrogen in boron steels particularly.Ferro Silicon Zirconium is the alloy of Iron Silicon and Zirconium produced by direct reduction of zircon sands in electric arc furnaces at high temperature. This alloy is used as Zirconium additive in steel melt, which reacts with Oxygen, Nitrogen and Sulphur.
