Abstract

In the cell for producing aluminium by decomposing alumina into aluminium metal, the alumina is dissolved in a cryolite bath. The cell has a carbon anode. In order to avoid breakdown, i.e. sputtering, of the anode, the cell is operated in such a way that a water-containing atmosphere is created at the anode. The water in this process may be contained in the alumina.
