EMD(Na、Co和Pb)的电子微探分析(Ⅲ)

Electron probe microanalysis of EMD(Na,Co and Pb)(Ⅲ)

对EMD进行电子微探分析(EPMA),发现Na、Co和Pb有浓缩点存在。Na在EMD颗粒表面的浓缩浓度达百分之几,Co、Pb的浓缩浓度最高达0.01%。

By electron probe microanalysis（EPMA）of electrolytic manganese dioxide（EMD）,Na,Co and Pb concentrating points were analyzed.The concentrating concentration of Na on the surface of EMD particle reached to several hundred percents.The highest concentrating concentration of Co and Pb was 0.01%.
