Abstract

1403183 Bipolar electrodes HOOKER CHEMICALS & PLASTICS CORP 15 May 1974 [25 May 1973(5)] 21601/74 Heading C7B A bipolar electrode useful in electrolysis of alkali metal chloride solutions to chlorates comprises a central layer of valve metal (i.e. which forms an inert anodic oxide film resistant to passage of electrons, e.g. Ti or Nb), covered at least in part on the anodic side with an electrically conductive, oxidation-resistant, electrolyte-insoluble material and having on its cathodic side a substantially hydrogen impermeable barrier layer of B, C, W, Si or a silicide (e.g. TiC). The anodic coating may be a Pt-group metal, oxide, alloy or mixture thereof, and may be applied by electro-plating or decomposition of an organo metallic compound under conditions which do not oxidize the valve metal. The barrier material may leave the valve metal applied thereto by sputtering. The valve metal layer may be at least 0.1 in. thick and the barrier layer 0.25 in. (graphite), 0.01-0.1 in. (B, W or Si) or 0.05-0.2 in. (TiC) thick.
