氯酸钾氧化Mn^(2+)沉积化学MnO_2及其特性研究

STUDIES ON THE CMD OBTAINED FROM OXIDIZING Mn^(2+)BY LiClo_3

在一定条件下,以氯酸锂氧化Mn^(2+)沉积的化学MnO_2(简称CMD),对其进行MnO_2含量、视比重、肼指数、磁化率、放电性能以及红外与差热分析.结果表明,为此制得的CMD电化活性较高,有望替代电解MnO_2(简称EMD)作为干电池的活性明极材料.

Mn^(2+) is oxidized by LiClo_3 under a certain conditions . The MnO_2 sample (NO, 1 )so obtained and the other two MnO_2 samples (No. 2 and No. 3)are characterised with chemical analysis (such as Mno_2 contenta, apparent density , hydrazine activity. magmetic susceptibility and discharge performance etc. )infred studies and differential thermal analysis. The results obtained from the above studies show that the Mno_2, sample (No. 1) promises as active cathod material in dry cells.
