Occurrence and Uses
Bayferrox 4330 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 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 triiron tetroxide:
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
Reactions
Bayferrox 4330, when heated at elevated temperatures with a reducing agent such as hydrogen or carbon monoxide in the absence of air, produces metallic iron:
Fe3O4 + 4H2 → 3Fe + 4H2O
Partial reduction gives iron(II) oxide. When treated with concentrated acids, the tetroxide dissolves in acids forming mixtures of iron(II) and iron(III) salts:
Fe3O4 + 8HCl → FeCl2 + 2FeCl3 + 4H2O
Fe3O4 + 4H2SO4 → FeSO4 + Fe2(SO4)3 + 4H2O

Bayferrox 4330 occurs in nature as the mineral magnetite.
Bayferrox 4330 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 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 exhibits permanent magnetism and is ferrimagnetic, but is sometimes incorrectly described as ferromagnetic.
Bayferrox 4330s 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.
Bayferrox 4330 is used as a black pigment and is known as C.I pigment black 11 (C.I. No.77499) or Mars Black.
Bayferrox 4330 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.
