By anodic oxidation, an aluminum plate can be covered with an amorphous or crystalline oxide layer, depending on the electrolyte used. The amorphous layer, obtained in a solution of oxalic or sulphuric acid, has a porous structure. However, the pores do not go right down to the aluminum as has been shown by many investigators, but end in a solic insulating layer, the thickness of which may be determined by capacity measurements.
Corresponding to a given temperature and solic concentration of the electrolytic solution and a given formation current density, there is only one final capacity obtainable. Increasing the concentration, or temperature, or decreasing the current density, increases the final capacity obtainable. / Science, Faculty of / Physics and Astronomy, Department of / Graduate
