Texture, growth and orientation of anodically formed silver oxides

Abstract

The structure, topography and growth of silver oxide deposits formed under galvanostatic and potentiostatic conditions in potassium hydroxide solutions has been studied by X-ray and electron diffraction and by electron microscopy. The argentous oxide deposit cannot be classified as being either continuous or discontinuous, but has features associated with both types of film. A random deposit is formed initially followed by the development of one-degree orientation. The argentous oxide film has a marked {111} orientation and a proportion of {112} orientation parallel to the electrode surface. Orientated argentic oxide deposits were not found under any conditions.
