Oxygen generating anode, and a manufacturing method thereof

A industrial electrolysis electrode covering the electrolyte active material layer, manufacturing and particularly electrolytic copper foil to reduce the oxygen overvoltage of oxygen generation for anodic used for metal sampling by electrolytic method, deposition of lead dioxide on the anode · coating was suppressed, and to provide an oxygen generating anodic and a manufacturing method thereof capable of enhancing the durability. And A conductive metal substrate in an oxygen-generating anode with a catalytic layer containing iridium oxide formed on the conductive metal substrate on, the catalyst layer is oxidized at high temperatures region of 410 ° C. to 450 ° C. is heated and calcined in the atmosphere, the catalyst layer is formed with mixed iridium oxide amorphous and crystalline, further, a catalyst layer with mixed iridium oxide amorphous and crystalline is further of 520 ° C. to 560 ° C. is post-baked in an oxidizing atmosphere at a high temperature region, the oxygen generating anode and a manufacturing method thereof, characterized in that a substantially whole amount of iridium oxide of the catalyst layer is crystallized. .The
