Iron Oxide
Iron oxides and oxyhydroxides are widespread in nature and play an important role in many geological and biological processes. They are used as iron ores, cosmetic pigments, tattoo inks, catalysts, and in thermite, and occur in hemoglobin. Iron oxides are inexpensive and durable pigments in paints, coatings and colored concretes.

Iron | Geoscience Australia
Iron and some alloys of iron are also magnetic. Iron is about eight times heavier than water (its relative density is 7.87). When iron is exposed to air it starts to turn back into iron oxide and the red powder that forms on the surface of iron is what we call rust. You may have seen rust on old cars or old iron sheds.

Abstract. Iron (III) oxide is a compound that appears in at least four different polymorphs: α-Fe 2 O 3, β-Fe 2 O 3, γ-Fe 2 O 3, and ε-Fe 2 O 3. However, Fe 3+ ions are also present in another form of iron oxide: Fe 3 O 4, which is an iron crystal structure with both Fe 2+ and Fe 3+ ions. And in its turn, Fe 2+ ions are also present in the ...
