| Abstract: | A selective dissolution method and a calculation method were combined to obtain the amount of different manganese ions (Mn 2+ ,Mn 3+ ,Mn 4+ ) in Mn 3O 4. According to the results, the mole ratio of manganese to oxygen was calculated,and possible distribution of various ions in Mn 3O 4 was proposed,which was consistent with the result of XRD. |
