•We report on the synthesis of phases in the Mn oxi-hidroxyde system in supercritical water.•Acetates were employed as precursors and only two high pressure pumps were used.•Synthesis conditions have been optimized concerning the flow rate and temperature.•Monodispersion and shape of nanoparticulated samples are characterized.
The synthesis of different phases in the manganese oxi-hidroxyde system has been achieved by using supercritical water from the manganese (II) acetate as precursor, using only two high pressure pumps. The synthesis conditions to obtain the Mn(OH)2 and Mn3O4 phases have been optimized concerning the temperature and the ratio between manganese solution and water flow rates as key parameters. All phases have been microstructurally characterized in features such as size, shape, size distribution and crystallinity. The magnetic response has been evaluated from magnetization experiments.
