An electrode suitable for separating chlorine in electrolysis cells consists of a metal substrate coated with two different compositions deposited in alternating layers, the first of which contains iridium oxides, ruthenium and valve metals, such as tantalum, and the latter contains oxides of iridium, ruthenium and tin. The electrode thus obtained combines the excellent characteristics of the anode potential and selectivity with respect to the chlorine release reaction. |
