ABSTRACT:
The invention relates to a method of forming an electrocatalytic surface on an electrode in a simple way, in particular on a lead anode used in the electrolytic recovery of metals. The catalytic coating is formed by a spraying method which does not essentially alter the characteristics of the coating powder during spraying. Transition metal oxides are used as the coating material. After the spray coating the electrode is ready for use without further treatment. The invention also relates to an electrode onto which an electrocatalytic surface is formed.
