Lead di:oxide electrode with titanium support comprises lead nitrate bath treated element with a preliminary mixed chromium and titanium oxide conducting layer

Electrode comprises an anode with formation of a conducting and anti-blocking layer of mixed chromium and titanium oxides, prior to deposition of the dioxide in a lead nitrate bath. To increase performance, the preliminary layer is applied through thermal decomposition of an alcoholic soln. contg. a mixture of chromium
and titanium chlorides. Electrode is used e.g. in solns. contg. chlorides and other electrochemical oxidn. processes.
