Occurrence and Uses:
Bayferrox 4330/3 occurs in nature as the mineral magnetite, the magnetic oxide of iron. This mineral along with hematite is used as the starting material for producing iron, steel and other ferro-alloys.
Preparation:
Bayferrox 4330/3 is obtained from its natural mineral magnetite. In the laboratory the compound may be prepared by adding sodium hydroxide solution to an aqueous solution of 1:2 molar mixture of ferrous and ferric salt. (i.e., 1 mol FeCl2 + 2 mol FeCl3). The resulting black precipitate of the hydroxide on heating dehydrates to gives Bayferrox 4330/3:
Fe2+(aq) + 2Fe3+(aq) + 8OH¯(aq) → Fe3(OH)8(s)
Fe3(OH)8(s) → Fe3O4(s) + 4H2O(g)
Also, the tetroxide may be produced by partial oxidation of iron or iron(II) sulfate by heating under limited amount of air. Another method of production involves heating iron metal with steam:
3Fe + 4H2O → Fe3O4 + 4H2
Chemical Properties:
Bayferrox 4330/3 constitutes the richest ore of iron; it is black and magnetic, one variety being called "lodestone".

Bayferrox 4330/3 is the chemical compound with formula Fe3O4.
Bayferrox 4330/3 occurs in nature as the mineral magnetite.
Bayferrox 4330/3 is one of a number of iron oxides, the others being iron(II) oxide (FeO), which is rare, and iron(III) oxide (Fe2O3) which also occurs naturally as the mineral hematite.
Bayferrox 4330/3 contains both Fe2+ and Fe3+ ions and is sometimes formulated as FeO ∙ Fe2O3. This iron oxide is encountered in the laboratory as a black powder.
Bayferrox 4330/3 exhibits permanent magnetism and is ferrimagnetic, but is sometimes incorrectly described as ferromagnetic.
Bayferrox 4330/3s most extensive use is as a black pigment. For this purpose, it is synthesized rather than being extracted from the naturally occurring mineral as the particle size and shape can be varied by the method of production.
Properties
Sample of magnetite, naturally occurring Fe3O4.
Bayferrox 4330/3 is ferrimagnetic with a Curie temperature of 858 K. There is a phase transition at 120K, called Verwey transition where there is a discontinuity in the structure, conductivity and magnetic properties.This effect has been extensively investigated and whilst various explanations have been proposed, it does not appear to be fully understood.
While it has much higher electrical resistivity than iron metal (96.1 nΩ m), Fe3O4's electrical resistivity (0.3 mΩ m ) is significantly lower than that of Fe2O3 (approx kΩ m). This is ascribed to electron exchange between the FeII and FeIII centres in Fe3O4.
Uses:
Bayferrox 4330/3 is used as a black pigment and is known as C.I pigment black 11 (C.I. No.77499) or Mars Black.
Bayferrox 4330/3 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.This iron–chrome catalyst is reduced at reactor start up to generate Fe3O4 from α-Fe2O3 and Cr2O3 to CrO3.
Bluing is a passivation process that produces a layer of Fe3O4 on the surface of steel to protect it from rust.
Ferumoxytol along with sulfur and aluminium, it is an ingredient in a specific type of thermite useful for cutting steel.
