摘　　要：研究了用硝酸溶解电解锰粉制备钽电容器用高纯硝酸锰。考察了分析纯硝酸和工业级硝酸的溶解特性,确定了硝酸锰溶液的浓缩方式。试验结果表明,用15%的分析纯硝酸溶解电解锰粉可以获得高纯硝酸锰溶液,溶液经浓缩、过滤,最终获得合格的钽电容器用高纯硝酸锰。Preparation of high purity in nitric acid was studied. The disso were examined, and concentrated way manganous nitrate using electrolytic manganese powder dissolved lution properties of analytic grade and industrial grade nitric acid of manganous nitrate solution were determined. The experimental results show that high purity manganous nitrate solution can be obtained using analytic grade nitric acid（15%）. After being concentrated and filtrated, the solution can be using to preparate tantalum capacitor.
