A new approximate equation is derived for the time variation of the ionic current during the constant voltage stage of anodic oxidation. By comparison with the exact solution, obtained by numerical integration, the error of the approximation can be kept below a limit of about 5%. which is much lower

An approximate equation is derived for the time variation of the ionic current during the constant voltage stage of the anodic oxidation process. The equation is given in terms of the normalized variables, ie the variable referred to its value during the constant-current stage. The influence of the
## Previous measurements of the current -voltage behaviour during anode effect in cryolite melts were extended to other NaF/AlF, ratios and to pure sodium halides. In all systems the current-voltage curves had similar shapes, showing several maxima and minima. The AE voltage range in which cryolit
