摘要
综述了化学二氧化锰的制备方法及国内外研究现状。介绍了几种常用的制备方法,碳酸锰热分解法、硝酸锰热分解法、氢氧化锰氧化法、硫酸锰氧化法和高锰酸盐还原法,并分析了这些制备方法的利弊。目前化学二氧化锰的主要工业生产方法是碳酸锰热分解法和硝酸锰热分解法。
Preparing methods and research status of chemical manganese dioxide at home and abroad were reviewed. Some preparing methods, such as manganese carbonate thermal decomposition method, manganese nitrate thermal decompo- sition method, manganese hydroxide oxidation method, manganese sulfate oxidation method, and permanganate reduction method ,were introduced. Then, advantages and disadvantages of these preparing methods were analyzed. At present, the main producing methods of chemical manganese dioxide are manganese carbonate thermal decomposition method and manga- nese nitrate thermal decomposition method.
