Constructed cathode used in the electrolysis of aqueous alkaline alkali chlorides comprises an electroconductive substrate coated with two layers containing oxides based on titanium, zirconium and a precious metal

摘要

A cathode comprising an electrically conductive substrate made of titanium, nickel, tantalum, zirconium, niobium, iron or alloys thereof, coated with an intermediate layer of oxides of titanium and of a precious metal, and with an outer layer comprising metal oxides of titanium, zirconium and a precious metal, can be used for the electrolysis of solutions, in particular for the electrolysis of aqueous solutions of alkali metal chlorides.
