摘要
研究了以铵盐作催化剂,利用高纯度锰粉悬浮液通空气催化氧化来制备高比表面四氧化三锰,并讨论了各因素对实验结果的影响,确定了反应的最佳条件;并对产品进行了检测和表征,经XRD检测确定产物为四氧化三锰。粒度分析仪测定产品的粒径小于4μm,比表面分析仪测定SBET比表面积可达15.06m2/g,锰的含量可达71.92％。
In this paper, the trimanganese tetroxide with high specific surface area was prepared by the oxidation of the manganese powder with the catalyst - ammonium salt,and the effected factors were discussed.Finally,the experimental optimization was found.The product done by oxidation according to the optimization was characterized and was determined. Specific surface area is 15.06m2/g,size of grain is less than 4um,content with manganese is 71.92% 0
