Manganese is present in two oxidation states +2 and +3 and the formula is sometimes written as MnO.Mn2O3. Mn3O4 is found in nature as the mineral hausmannite. ==Preparation== Mn3O4 formed when any manganese oxide is heated in air above 1000 °C. Considerable research has centred on producing nano-crystalline Mn3O4 and various syntheses that involve oxidation of MnII or reduction of MnVI.〔Hausmannite Mn3O4 nanorods: synthesis, characterization and magnetic properties Jin Du et al.
