Iron Oxide Formula

Iron Oxide formula for Iron(III) oxide or ferric oxide formula is discussed in this article. This inorganic compound with a chemical formula Fe2O3. The main oxides of iron are FeO or iron(II) oxide, (Fe3O4) or iron(II, III) oxide, and iron(III) oxide. Iron(III) oxide is also called by the name hematite. It is It is a rock-forming mineral which is found in metamorphic, igneous, and sedimentary rocks. Acids readily attack it and therefore it is often called rust. The composition of pure hematite by weight is 70% iron and 30% oxygen.
