（重定向自Red iron oxide）

Two different colors at different hydrate phase (α = red, β = yellow) of iron(III) oxide hydrate[3] and they are useful as a pigment.

氧化铁，或称三氧化二铁，化学式Fe₂O₃，是铁锈和赤铁矿的主要成分。铁锈的主要成因是铁金属在杂质碳的存在下，与环境中的水份和氧气反应，铁金属便会生锈。

It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare, and iron(II,III) oxide (Fe₃O₄), which also occurs naturally as the mineral magnetite. As the mineral known as hematite, Fe₂O₃ is the main source of iron for the steel industry. Fe₂O₃ is ferromagnetic, dark red, and readily attacked by acids. Iron(III) oxide is often called rust, and to some extent this label is useful, because rust shares several properties and has a similar composition. To a chemist, rust is considered an ill-defined material, described as hydrated ferric oxide.
