摘要：
A manganese dioxide layer of improved quality is formed on the surface of a dielectric oxide coating on a valve-metal substrate by repeating sequential procedures of immersing the substrate in an aqueous solution of manganese nitrate and heating the wet substrate to cause pyrolytic decomposition of manganese nitrate several times on condition that the heating is carried out at least once in a furnace wherein hot air flows and at least once in a semi-closed radiant furnace wherein the decomposition proceeds under a positive pressure of a small magnitude due to prolonged retention of gaseous decomposition products in the heating chamber.
