Abstract

Procédé de fabrication d'une électrode anodique stable en dimensions du type comprenant une âme en matière électroconductrice et un revêtement conducteur électrocatalytique, caractérisé en ce que l'on réalise d'abord une âme électroconductrice en un métal commun tel que du fer, un alliage de fer, de l'aluminium fondant à haute température, en ce qu on introduit ensuite ladite âme dans un premier bain électrolytique fondu à haute température constitué d'un mélange d'halogénures alcalins et d'halogénures de métaux d'arrêt, pour former un premier revêtement conducteur sur l'âme, et en ce que l'on introduit ensuite ladite âme moulée munie de son premier revêtement dans un second bain électrolytique fondu à haute température constitué d'un mélange d'halogénures de métaux nobles et de métaux d'arrêt, pour former un second revêtement conducteur électrocatalytique sur l'âme moulée munie de son premier revêtement conducteur. Application aux cellules électrolytiques de solutions de sels ou de sels fondus.A method of manufacturing a dimensionally stable anode electrode of the type comprising a core of electroconductive material and an electrocatalytic conductive coating, characterized in that first an electroconductive core is made of a common metal such as iron, an alloy iron, aluminum melting at high temperature, in that said core is then introduced into a first electrolytic bath melted at high temperature consisting of a mixture of alkali halides and halides of stop metals, to form a first conductive coating on the core, and in that said molded core provided with its first coating is then introduced into a second high-temperature molten electrolytic bath consisting of a mixture of noble metal halides and metals of 'stop, to form a second electrocatalytic conductive coating on the molded core provided with its first conductive coating. Application to electrolytic cells of solutions of salts or molten salts.
