<p>Carbon-containing components, in particular sidewalls, of cells for the production of aluminum by the electrolysis of alumina dissolved in a cryolite-based molten electrolyte are protected from attack by liquid and/or gaseous components of the electrolyte, by a treatment composition which consists essentially of a solution of one or more non-colloidal phosphates of aluminum. The treatment composition may alternatively consist essentially of one or more non-colloidal phosphates of aluminum and one or more colloidal carriers.</p> |
