Abstract

An electrode useful as an anode for the electrolysis of aqueous solutions of ionizable chemical compounds, and especially the electrolysis of brines comprises an electroconductive substrate, such as a valve metal having a coating thereon of electroconductive tin oxide containing about 0.1 to about 15 mole percent of niobium based on the moles of tin. An additional electrocatalytic phase may be present as a minor component of the tin oxide coating and/or as a coating thereon.
