Iron(II) oxide or ferrous oxide is the inorganic compound with the formula FeO. Its mineral form is known as wüstite . [ 3 ] [ 4 ] One of several iron oxides , it is a black-colored powder that is sometimes confused with rust , the latter of which consists of hydrated iron(III) oxide (ferric oxide).

Iron(II,III) oxide, or black iron oxide, is the chemical compound with formula Fe 3 O 4.It occurs in nature as the mineral magnetite.It is one of a number of iron oxides, the others being iron(II) oxide (FeO), which is rare, and iron(III) oxide (Fe 2 O 3) which also occurs naturally as the mineral hematite.
Iron forms various oxide and hydroxide compounds; the most common are iron(II,III) oxide (Fe 3 O 4), and iron(III) oxide (Fe 2 O 3). Iron(II) oxide also exists, though it is unstable at room temperature.
Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe 2 O 3. 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(II) oxide (ferrous oxide), FeO, is a very complicated material that contains iron(II). Iron(II) is found in many minerals and solids. Examples include the sulfide and oxide, FeS and FeO. These formulas are deceptively simple because these sulfides and oxides are often nonstoichiometric.
The formula for magnetite is more accurately written as FeO·Fe 2 O 3 than as Fe 3 O 4. Magnetite is one part FeO and one part Fe 2 O 3, rather than a solid solution of wüstite and hematite. Magnetite is termed a redox buffer because, until all Fe 3+ present in the system is converted to Fe 2+, the oxide mineral assemblage of iron remains
An oxide (/ ˈ ɒ k s aɪ d /) is a chemical compound containing at least one oxygen atom and one other element [1] in its chemical formula. "Oxide" itself is the dianion (anion bearing a net charge of –2) of oxygen, an O 2– ion with oxygen in the oxidation state of −2. Most of the Earth's crust consists of oxides. Even materials ...
