Suspension bath and process for production of electrolytic manganese dioxide.

摘要

The present invention provides a bath for the production of electrolytic manganese dioxide, characterized in that the bath comprises (a) between about 0.5 and about 1.3 moles/liter of an aqueous solution of at least one manganese salt selected from manganese sulfate, manganous chloride, manganous nitrate; (b) a sufficient quantity of at least one acid selected from sulfuric acid, hydrochloric acid and nitric acid so that the pH of said bath is between about 1 and about 2; and (c) at least one suspension agent which is selected from insoluble multivalent elements and of insoluble compounds of multivalent metals other than manganese and the use of such a bath.
