ABSTRACT:
An electrode suitable for use in an electrolytic cell is dissolved. The electrode comprises: an electroconductive substrate with at least a portion of the surface thereof being a solderable metal. The electroconductive substrate abuttingly joins a film-forming metal by means of an electrically conductive, fused, non-ferrous bonding layer interposed between the solderable metal surface of the substrate and the inner surface of the film-forming metal. At least a portion of the inner surface of the film-forming metal is a solderable metal. At least a portion of the outer surface of the film-forming metal is electrocatalytically active and corresponds at least partially to the working area of the electrode. A method of producing the electrode, and its use as an anode in the electrolytic production of chlorine are also disclosed.
