1,201,806. Making electrode assemblies. GEORGE KENT Ltd. 4 Nov., 1968 [23 Nov., 1967], No. 53424/67. Heading B3A. [Also in Division G1] An electrode for a galvanic cell comprises an impermeable lime-stabilized zirconium oxide tube 1 to which are attached platinum electrodes 2, 3 and an overlayer, 6, of porous zirconium oxide. The overlayer may be attached by firing a paste of finely divided zirconium oxide and a glycerine binder at 1750‹ C. on to the tip of the tube, or by flame spraying. The electrodes may be attached by either of these methods. Yttriastabilized thoria may be used instead of zirconium oxide. |
