摘要
在相同条件下,以碱金属和碱土金属的氯酸盐氧化Mn^(2+),对如此得到的合成MnO_2试样进行化学分析(如MnO_2含量、肼指数,视比重、磁化率和放电性能等)、红外光谱分析和差热分析,结果表明。
Mn^(2+) is oxidized by alkali metal chlorates and alkali-earth metal chlorates under the same reaction conditions.A number of the Synthetic MnO:samples so obtained are characterised by chemical an alysis (such as MnO_2 contents.hydrazine activity index,apparentdensity, magnetic susceptibility and discharge performance etc.). infa-red studies and differential thermal analysis.The results obtained from the above studies reveal that the samples prepared in this laboratory show promise as active cathode materials in dry cells.
