VALVE METAL/PLATINUM COMPOSITE ELECTRODE

摘要

The present invention provides a process for the production of a composite electrode based on a valve metal with a layer of a platinum foil securely adhering thereto by the hot isostatic pressing of metal base and platinum foil between separating sheets, wherein as that separating sheet which, in the case of the hot isostatic pressing, comes to lie in contact with the platinum foil, there is used a metal with a melting temperature of at least 100.degree.C. above the hot pressing temperature employed. The electrode obtainable by the process according to the present invention can be used for carrying out anodic oxidations.
