Chemical Manganese Dioxide(CMD)was prepared by an alkali-oxidation method.There are several virtues to this environmental friendly and clean process,including the nontoxic and harmless reagents and products,easy operations,no pollutants,easily obtained raw materials and moderate reaction conditions.The synthesized manganese dioxide was characterized by XRD and SEM.The particles were small,consisting primarily of α-MnO2 and γ-MnO2.Experimental results showed that the optimum 11; reaction time and temperature,20 min and 80 ℃; air flow,0.20 m3/h; and,agitation rate,700 r/min.The conversion of MnSO4can exceed 80% under these optimum conditions.
