Iron (II) oxide or ferrous oxide is the inorganic compound with the formula FeO. Its mineral form is known as wüstite. [3][4] One of several iron oxides, it is a black-colored powder that is sometimes confused with rust, the latter of which consists of hydrated iron (III) oxide (ferric oxide).
The brown color indicates that iron is at the oxidation state +3. Green and reddish brown stains on a limestone core sample, respectively corresponding to oxides/hydroxides of Fe 2+ and Fe 3+. Iron oxides feature as ferrous (Fe (II)) or ferric (Fe (III)) or both.
Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe 2 O 3. It occurs in nature as the mineral hematite , which serves as the primary source of iron for the steel industry. It is also known as red iron oxide , especially when used in pigments .
