摘要
研究了在稀酸性介质中,锰盐与氧化剂反应制备化学二氧化锰时,杂质离子(Na^+或K^+)对试样二氧化锰的性能和结构的影响。测定了试样中二氧化锰的含量、拍实比重、磁化率、X射线衍射数据。结果表明掺有钠离子的试样性能较优。
The manganese dioxides prepared by oxibizing agent of Mn(Ⅱ) salts has been studied. The structure and property of MnO_2 is found to be greatly influenced by impurity ion. The samples are determined by chemical analysis, tapping Density, X—ray magneti suscaptibility. These results show the presertce of Na^+ ions have better characteristics.
