Iron oxides are chemical compounds composed of iron and oxygen. Several iron oxides are recognized. All are black magnetic solids. Often they are non-stoichiometric. Oxyhydroxides are a related class of compounds, perhaps the best known of which is rust. Iron oxides and oxyhydroxides are … See more Iron oxides feature as ferrous (Fe(II)) or ferric (Fe(III)) or both. They adopt octahedral or tetrahedral coordination geometry. Only a few oxides are significant at the earth's surface, particularly wüstite, … See more • goethite (α-FeOOH), • akaganéite (β-FeOOH), • lepidocrocite (γ-FeOOH), • feroxyhyte (δ-FeOOH), • ferrihydrite (Fe5HO8 · 4 H2O approx., or 5 Fe2O3 · 9 H2O, better recast as FeOOH · 0.4 H2O) See more • Great Oxidation Event • Iron cycle • Iron oxide nanoparticle • Limonite • List of inorganic pigments See more In blast furnaces and related factories, iron oxides are converted to the metal. Typical reducing agents are various forms of carbon.
