Is Fe2O3 and Fe3O4 same?
What is the difference between Fe2O3 and Fe3O4? They are ferrous oxides. Thus, Fe2O3 is a simple oxide where Fe is only + 3 in the oxidation state thus Fe3O4 is a mixed oxide where Fe is present in both + 2 and + 3 oxidation states.
Is Fe3O4 rust?
Magnetite (or Fe3O4) is an elaborate kind of rust – a regular lattice of oxygen and iron atoms. The properties of magnetite are governed by missing iron atoms in the sub-surface layer.
What is Fe2O4 called?
Iron oxide (Fe2O4)
Is Fe3O4 ferrimagnetic?
The magnetic interaction among iron ions at octahedral and tetrahedral sites is antiferromagnetic and that among octahedral ions is ferromagnetic; overall a ferrimagnetic arrangement of Fe3O4. Therefore, the net magnetic moment in Fe3O4 is due to Fe2+ ions (4 μB).
What is Fe3O4 structure?
Iron(II,III) oxide is the chemical compound with formula Fe3O4. It occurs in nature as the mineral magnetite. It contains both Fe2+ and Fe3+ ions and is sometimes formulated as FeO ∙ Fe2O3.
How is the formula Fe3O4 derived?
Fe3O4 is formed with the combination of FeO and Fe2O3 i.e. ferrous oxide and ferric oxide.
What is the molar mass of Fe3O4?
231.53

What is Fe3O4 used for?
Fe3O4 is used as a black pigment and is known as C.I pigment black 11 (C.I. No.77499) or Mars Black. Fe3O4 is used as a catalyst in the Haber process and in the water-gas shift reaction. The latter uses an HTS (high temperature shift catalyst) of iron oxide stabilised by chromium oxide.
How was magnetite formed?
Magnetite forms in small quantities interspersed with many iron-rich minerals, but only forms bodies of crystals on its own when mafic magma, a very liquid magma laden with heavy elements, cools sufficiently slowly for individual crystals to clump together.
What is the formula for iron III oxide?
The formula of the chemical compound Iron(III) oxide is Fe2O3
What is the chemical equation for iron oxide?
It is also known as iron (III) oxide and its chemical formula is Fe2O3. It is an inorganic compound. The other two oxides of iron are iron (II) oxide having the chemical formula FeO and iron (II,III) oxide having the chemical formula Fe3O4.
