Preparation and characterisation of chemical manganese dioxide: Effect
Electrolytic manganese dioxide can be produced by purified manganese sulphate solutions, acidified by H 2 SO 4 and subjected to electrolysis at 90–98 °C. By this way MnO 2 is deposited (14–20 days) as a solid coating on the anode with yields ranging from 70 to >90%. Nowadays this technology is generally employed for synthetic manganese dioxide used in the …
