STABLE COATING SOLUTIONS FOR PREPARING IMPROVED ELECTROCATALYTIC MIXED OXIDE COATINGS ON METAL SUBSTRATES OR METAL-COATED CONDUCTIVE SUBSTRATES, AND DIMENSIONALLY STABLE ANODES PRODUCED FROM SUCH SOLUTIONS

摘要

Stable coating solutions are prepared for the application of improved electrocatalytic, mixed oxide coatings, using soluble compounds of at least two platinum group metals and at least one soluble compound of a valve metal which are solubilized in an anhydrous solvent mixture. Dimensionally stable anodes including mixed oxide catalytic coating layers from these solutions possess a longer useful life.
