The rate of nucleation of the anodic oxide film on bismuth in 0.1 M NaOH is limited hy electrochemical reaction at the uncovered metal surface or surface diffusion to the periphery of a spreading oxide patch, not by incorporation into the growing lattice. Anodic oxide layers grown on bismuth consist

The early stages in the formation of a continuous anodic layer of bismuth oxide on a solid bismuth electrode, in the pH range 5-14, were studied. The oxide covered the surface by the simultaneous thickening and spreading of patches. The metal surface was classified into two different areas with diff
