Patent ID: 8366889

Claim:
An anode for electrolysis, comprising: a substrate comprising titanium or titanium alloy, and a plurality of coating layer provided on the surface of the substrate by the thermal decomposition baking method, wherein the coating layer comprising: the first coating layer comprising a mixture of iridium oxide, ruthenium oxide and titanium oxide, provided on the surface of the substrate, the second coating layer comprising a mixture of platinum and iridium oxide, provided on the first coating layer, a unit layer comprising the first coating layer and the second coating layer, provided on the surface of the second coating layer by a single or a plurality of layer, and the second coating layer, provided on the outermost layer of the unit layer, characterized in that a plurality of coating layer is provided on the surface of the substrate by means of the thermal decomposition baking method, followed by post-baking at a baking temperature higher than that by the thermal decomposition baking method.
