The anodic oxidation of the binary compounds of the transition elements in sulphuric acid

  • R. D. Armstrong

The anodic oxidation of the silicides and carbides of Ta, W and Mo in M H2SO2 has been studied. The rate of corrosion has been shown to be dependent on the solubility of the reaction products. Oxidation of the carbides of Ta and W produces a carbon rich surface. This may be an important factor in the enhanced catalytic activity for hydrogen oxidation shown by anodized tungsten carbide.
