Beschreibung
Zusammenfassung:	The invention relates to a process for the production of composite electrodes for electrochemical processes which are produced from a valve metal base and a coating, strongly adherent thereto, of platinum foil by high-temperature isostatic pressing of the base metal and the platinum foil between layers of release agent. The release agent which comes into contact with the platinum foil is a foil made from a metal having a high melting point, preferably having a diffusion-barrier layer. A ceramic foil which is free from carbon or C-eliminating compounds can likewise be used with subsequent cleaning of the platinum surface of the HIP composite material.
