Iron oxide - Wikipedia
Iron oxides are chemical compounds composed of iron and oxygen. Several iron oxides are recognized. Often they are non-stoichiometric. Ferric oxyhydroxides are a related class of compounds, perhaps the best known of which is rust. [1] Iron oxides and oxyhydroxides are widespread in nature and play an important role in many geological and ...

Iron(III) oxide - Wikipedia
Iron (III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. 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.
Iron Oxide - Structure, Properties, Preparation and Uses - Vedantu
Iron oxide, which is also called ferric oxide, is an inorganic compound having the chemical formula Fe 2 O 3. It is one of the 3 major oxides of iron, and the remaining two being iron(II) oxide (FeO), which is the rare iron (II, and III) oxide (Fe 3 O 4 ), and also naturally takes place as the mineral magnetite.
Iron Oxide - an overview | ScienceDirect Topics
Iron oxide is the most common and naturally found oxide. Iron in oxide may have two valent states, Fe (II) and Fe (III). Due to unpaired electrons present in Fe (II) and Fe (III), these oxides show magnetic behaviour and used efficiently as adsorbent for arsenic water remediation.
Iron Oxide - an overview | ScienceDirect Topics
Iron oxides are abundant minerals on earth and play an important role in a variety of applications ranging from geochemistry, weathering, corrosion science, biomedicine, magnetic devices to heterogeneous catalysis, and photocatalysis. The surface chemistry of these oxides is dominated by interactions with water and solvated ions.
