ABSTRACT:
The present invention relates to a method of producing an electrolytic electrode containing the following steps: forming a lead plating layer on the surface of a metallic core material by using a lead electrolytic plating bath, where the metallic core material is the cathode; forming an .alpha.-lead dioxide layer on the lead plating layer by electrolysis using an alkaline bath containing a lead ion and using the core material as the anode; and forming a .beta.-lead dioxide layer on the .alpha.-lead dioxide layer by electrolysis using an aqueous lead nitrate solution and using the core material as the anode. The electrolytic electrode produced by the foregoing method is capable of electrolysis in an aqueous solution, in particular, in an aqueous corrosive solution containing fluorine ions.
