    Abstract: An improved electrode having an electroconductive metal support or core at least superficially made of titanium or a titanium alloy and a catalytic coating on the titanium metal surface including (a) at least one substance from the group consisting of the platinum group metals and their oxides and (b) an oxide of tellurium. This novel electrode is particularly adapted for use in the electrolysis of aqueous solution of alkali metal halides.

    Abstract: 1384793 Iridium oxide SOLVAY ET CIE SA 24 May 1972 [2 June 1971 4 May 1972] 24452/72 Heading C1A [Also in Division C7] A method of manufacturing an electrode with an Ir or Ir oxide coating comprises applying to a substrate of Ti or Ti alloy (optionally carrying a thin surface layer of TiO 2 ), a coating composition comprising thermally decomposable compounds of Ir and of at least one of Li, B, Be, Mg, Ga and Ge in a liquid vehicle. The liquid vehicle may be amyl alcohol, butyl alcohol, isopropyl alcohol, propylene carbonate, dimethyl formamide, dimethyl sulphoxide, dilute HCl, or mixtures thereof. The Ir compound can be any compound that decomposes to the metal and/or oxide, e.g. hexachloroiridic acid. The substrate is cleaned and etched, after which the coating is applied by brushing, spraying, atomizing or immersion, dried and heated in an oxidizing atmosphere to produce Ir in the metallic or oxidized state. The coated substrate may be subsequently coated with a Pt metal or compound. The substrate may be coated and heated to form successive layers. The atomic proportion of Ir to other said element(s) lies between 1/4 and 8/1. Several examples of coating compositions are given.

    Abstract: 1358926 Electrocatalysts; coated electrodes SOLVAY ET CIE 29 July 1971 [29 July 1970] 35747/71 Headings B1E and B2E [Also in Divisions C7 and H1] Electrodes comprise a coating of catalytic material on a support made at least superficially of titanium or a titanium alloy, the catalytic material comprising one or more elements of the platinum group in the metallic and/or oxidised state and tellurium in the oxidised state. The tellurium may be partially replaced by molybdenum or tungsten and the catalytic material may also comprise chromium lead, bismuth, antimony, tin, cadmium, titanium, tantalum and/or niobium in the oxidised state. In the examples the compounds of the catalytic elements are applied in solution in an organic solvent to form a coating and the coated structure is heat-treated. The electrodes are tested in the electrolysis of brine with a flowing mercury cathode to produce chlorine. They can also be used in cathodic protection, water purification, other electrolytic processes and as fuel cell electrodes.
