Ag（Ⅰ）电解催化剂Mn（Ⅱ）制备MnO2的研究—（Ⅲ）产品MnO2的物化特性

Studies on the Preparation of MnO_2 by Catalysis of Mn(Ⅱ) Anodic Oxidation by Silver (Ⅰ)——(Ⅲ) The Physical and Chemical Characteristics of Product MnO_2

本文对用新方法－Ag（Ⅰ）电解催化剂Mn(Ⅱ)阳极氧化法－制备出的新型MnO2，进行化学成份、活性、比表面积、视比重、红外光谱以及差热曲线等用物理化学性能的分析，确定了所制备的新型MnO2的特性。分析结果表明，所制备的新型MnO2比用传统的电解法制备的电解MnO2具有较优的物理化学性质。

Some physical and chemical properties of the product MnO2 preparep by catalysis of Mn (Ⅱ) anodic oxidation by silver (Ⅰ) were studied. The results show that the product MnO2 has higher activity, more amount of combined water and larger apparent surface than the electrolytic manganese dioxide.
