## Abstract The anodic behaviour of silver was investigated in cryolite—alumina-based melt. Silver has a lower melting point (ca. 960°C) than the other metals considered as possible inert materials for aluminium electrolysis. The working temperature used in aluminium industry is approximately 960°C

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%
