Abstract

Electrodes for electrolytic processes comprise an electrically-conductive and corrosion-resistant substrate, having a coating thereon which contains a solid solution of tin dioxide and bismuth trioxide, preferably in a ratio of 9:1 to 4:1 by weight of the respective metals. This solid solution may form the active coating or an intermediate layer covered with other electrocatalytic materials or may be included in a multi-component coating having selective properties for halogen evolution and oxygen inhibition.
