Summary:The invention relates to a catalytic coating suitable for oxygen-evolving anodes in electrochemical processes. The catalytic coating comprises an outermost layer with an iridium and tantalum oxide-based composition modified with amounts not higher than 5% by weight of titanium oxide. L'invention concerne un revêtement catalytique approprié pour des anodes dégageant de l'oxygène dans des procédés électrochimiques. Le revêtement catalytique comprend une couche extérieure dotée d'une composition à base d'oxyde de tantale et d'iridium modifiée par des quantités inférieures ou égales à 5% en poids d'oxyde de titane.
