Triiron tetraoxide Chemical Properties,Uses,Production
Physical Properties
Black cubic crystal or amorphous powder; refractive index 2.42; density 5.17 g/cm3; Moh’s hardness 6.0; melts at 1,597°C; insoluble in water, soluble in acids.
Occurrence and Uses
Triiron tetroxide 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
Triiron tetroxide 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
Triiron tetroxide, 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
Chemical Properties
Magnetite (Fe3O4) constitutes the richest ore of iron; it is black and magnetic, one variety being called "lodestone".
Chemical Properties
solid
Uses
Iron(II,III) oxide (Fe3O4) can be used as a heterogeneous catalyst for the Fenton type oxidation of rhodamine B. It can be used as an anode material for the fabrication of lithium-ion batteries. Fe3O4 can also be utilized in the catalysis of the oxygen reduction reaction (ORR) in the anion exchange membrane fuel cell.
Uses
Mostly it is used as a black- pigment -catalyst in the Haber process and in the water gas shift reaction. It is used as a contrast-agent in MRI scanning, whereas it is used as a pigment in magnetic applications, polishing compounds, cosmetics, medicines, polymer, rubber, filler, building, construction, appliances, and magnetic inks.
Uses
Triiron tetraoxide can be used as pigment in paints, linoleum, ceramic glazes; in coloring glass; as a polishing compound; in the textile industry; in cathodes; as catalyst.
