<p>1354897 Anodes for use with Hg cathodes IMPERIAL CHEMICAL INDUSTRIES Ltd 24 Feb 1972 [22 March 1971] 7467/71 Heading C7B [Also in Divisions B2 and H1] An electrode, e.g. for use in electrolysis of alkali metal chloride using a mercury cathode, fuel cells, electro-synthesis or cathodic protection comprises a support member of titanium, zirconium, niobium, tantalum or tungsten or an alloy thereof having a coating consisting of (a) ruthenium dioxide, (b) titanium dioxide, and (c) one or more of tin dioxide, germanium dioxide and oxides of antimony. The coating may be applied as a paint composition of thermally decomposable compounds of ruthenium, e.g. ruthenium trichloride or ruthenium resinate; tin, germanium and/or antimony, e.g. alkoxides, alkoxyhalides or halides; and organo-compounds of titanium, e.g. alkyl titanate or alkyl halotitanate, and an organic liquid, e.g. pentanol, and thereafter heating to at least 350‹ C in an oxidizing atmosphere to convert the metal compounds to the oxides thereof. The coating may be formed by sequential production of a plurality of such layers.</p> |
