摘要
本文研究了在稀盐酸介质中,2价锰盐与氧化剂A反应的最佳试验条件。制得二氧化锰试样的特性,用化学分析、红外光谱、差热分析进行了测定,结果令人满意,可望做为干电池的阴极活性物质。
In this paper the optimum conditions necessary for complete oxida-tion of manganous salts by oxidizing agent A in dilute hydrochloric acidmedium has been studied.This oxide so obtained was characterised bychemical analysis, infra-red spectrometry and differential thermal anal-ysis studies. These results all are satisfactory. It can be expected th-at, MnO_2 prepared by such method may be used as an active canthodematerials in dry cell.
