ELECTRODE SUITABLE FOR OPERATING AS AN ANOD IN ELECTROLYTIC CELLS, PROCESS FOR MANUFACTURE OF ELECTROLYTE CELL, ELECTROLYTIC CELL AND CHLORINE AND ALKALINE PRODUCTION PROCESS

摘要

Suitable electrode for operating as an anode in electrolytic cells, process for manufacturing said electrode, electrolytic cell and chlorine and alkaline production process The present invention relates to an electrode formulation comprising a catalytic layer containing tin oxides , ruthenium, iridium, palladium and niobium applied to a titanium or other valve metal substrate. A protective layer based on titanium oxide modified with oxides of other elements such as tantalum, niobium or bismuth may be interposed between the substrate and the catalytic layer. The electrode thus obtained is suitable for use as an anode in electrolyte cells for chlorine production.
