摘要
在相同条件下,以碱金属和碱土金属的氯酸盐氧亿Mn^(2+),对如此得到的合成MnO_2进行结构及放电性能的研究,结果表明,它们都属r-MnO_2且放电性能与相应的氧化剂中金属阳离子半径变化有一定关系,并从MnO_2的半导体性质方面作出理论上的解释。
Mn^(2+)is oxidized by alkali metal chlorates and alkali- earthmetal chlorates under the same reaction conditions.A number of the synthetic MnO_2 samples so obtained are studied on their construction and discharge performance.All of above MnO_2 samples are r-MnO_2 and the discharge performance of them has a correlation with chan- ges of the mental ionic redius in the oxidents.An attempt is made to explain this correlation theoretically in semi-conductor.
