ABSTRACT:
An electrochemical process for producing manganese dioxide by electrolysis of a solution of manganese sulphate containing 100 to 150 g/l of manganese sulphate and 20 to 30 g/l of sulphuric acid and having a temperature of from 90.degree. to 95.degree. C at an anodic current density of from 80 to 100 A/m.sup.2 using a titanium anode coated with a layer of titanium carbide with a thickness of from 50 to 100 mcm and a cathode. The resulting manganese dioxide is useful in the production of electric cells as the active mass of the positive electrode fo manganeze-zinc chemical sources of current.
