| Preparation | Pure manganese(IV) oxide (precipitate form) may be prepared by reducing permanganate ion with a manganous salt: 2KMnO4 + 3MnSO4 + 2H2O → 5MnO2 + K2SO4 + 2H2SO4 Manganese(IV) oxide can also be precipitated by oxidation of a manganese(II) salt using an oxidizing agent such as hypochlorite or peroxydisulphate: Mn2+ + S2O82– + 2H2O → MnO2 + 2SO42– + 4H+ Manganese(IV) oxide may also be made by thermal decomposition of manganese(II) nitrate; or from roasting manganese(II) carbonate in air: Mn(NO3)2 → MnO2 + 2NO2 MnCO3 + ½ O2 → MnO2 + CO2 A highly active gamma-MnO2 can be produced by treating manganese(III) oxide with hot sulfuric acid: Mn2O3 + H2SO4 → MnO2 + MnSO4 + H2O Mn2O3 is derived from pyrolusite by heating the mineral at 600–800°C or reducing with powdered coal at 300°C. |
What are the main uses of Manganese Dioxide?
Manganese dioxide (MnO2) is soluble in water and HNO3 and soluble in HCl. It occurs in nature as the blue-black mineral pyrolusite. In glass, manganese dioxide is used as a colorant and decolorizer.
The major use of manganese oxides is an ore of manganese for the manufacturing of steel; manganese serves to increase the hardness and decrease the brittleness of steel. Another important use of manganese oxides is as the cathode material of common zinc/carbon and alkaline batteries (such as flashlight batteries).
