尖晶石型四氧化三锰中Mn^(2+)、Mn^(3+)、Mn^(4+)的测定方法和离子分布的研究

Stuty on Determination of Mn^(2+),Mn^(3+),Mn^(4+) and Their Distribution in Tetragonal Spinel type Mn_3O_4

采用选择性溶解法和计算法结合的方法 ,测定了四氧化三锰中 Mn2 +、Mn3+、Mn4 +的含量 ,求出了四氧化三锰中的锰氧摩尔比和三种不同价态的锰离子在尖晶石中的离子分布式 ,进而确定其结构。分析结果与

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.
