The iron in the primary mill scale is usually present in different chemical forms. The primary scale has three layers of iron oxides consisting of wustite (mostly FeO), magnetite (Fe3O4), and hematite (Fe2O3) from the metal surface outwards. Wustite is the inner most phase of the scale which forms next to the metal and is the Fe rich phase.
