Abstract
Results are presented from a study of the influence of bath composition, temperature, cathodic current density, interpolar distance and bath impurities on the current efficiency with respect to aluminium in a laboratory cell. The current efficiency was determined from the weight gain of the metal pad, in a laboratory cell specifically designed to attain good and reproducible convective conditions, and with a flat aluminium cathode surface which ensures even current density distribution on the aluminium pad surface. The cell is believed to more closely represent conditions in commercial cells than traditional small scale laboratory cells. The results are compared to previously reported results, and a current efficiency model is presented.
