Electrolyte for impregnation of electrolytic capacitors with manganese dioxide and method of making it.

摘要

Process for the manufacture of a manganese nitrate-based electrolyte for the impregnation of electrolytic capacitors using manganese dioxide, starting with an acidic master solution obtained by reaction of manganous carbonate MnCO3 with nitric acid HNO3, the process consisting in adding manganese dioxide and aqueous hydrogen peroxide to the master solution. The invention also relates to the electrolyte obtained by this process.
