Abstract: The solubility of alumina was determined in electrolytes used in aluminum three-layer refining, based on the mass loss of a rotating alumina disk. Solubilities at 750°C were 0.97 mass % Al2O3 and 1.49 mass % Al2O3 for the so-called Pechiney and Alusuisse electrolytes, respectively, while other proposed electrolyte compositions showed lower solubilities.
