## 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

The anode gas evolved during anode etIbct (AE) in NasAlF,-AlsO3 melts consists essentiahy of CO, CO, and CFI. The gas composition was found to be very sensitive to the ahunina concentration and to the AE voltage. In laboratory cells the CF, content ranged from 80 % in putSed cryolite to less than 1%
