氯酸钡氧化Mn^(2+)沉积法制化学MnO_2及其特性研究

Studies on the CMD Obtained from Oxidizing Mn^(2+) by Ba(ClO_3)_2

在一定条件下,以氯酸钡氧化Mn2+ 沉积法制化学MnO2 (简称CMD),对其进行MnO2 含量、肼指数、磁化率、放电性能以及红外与差热等分析。结果表明:制得的CMD电化学活性较高,有望替代电解MnO2(简称EMD)作为干电池的阴极活性材料。

Mn 2+ is oxidized by Ba(ClO 3) 2 under certain conditions .The MnO 2 sample(No.1) so obtained and the other two MnO 2 samples (No.2 and No.3)are characterised by chemical analysis (such as MnO 2 contents,hydrazine activity,magnetic susceptibility and discharge performance etc.),infrared studies and differential thermal analysis.The results obtained from the above studies show that the MnO 2.sample (No.1)promises as active cathode material in dry cells.
