ABSTRACT:
A manganese dioxide layer of improved quality is formed on an anodized valve metal substrate by repeating only a few times the steps of immersing the substrate in an aqueous solution of manganese nitrate and heating the wet substrate to cause pyrolytic decomposition of manganese nitrate to manganese dioxide in a semiclosed radiant furnace, wherein the decomposition proceeds under a positive pressure of a small magnitude due to prolonged retention of gaseous decomposition products.
