Abstract
A potentiostatic double pulse method has been developed for the measurement of current efficiency of aluminium deposition from cryolitic melts on solid substrates. The method is based on the measurement of the ratio of anodic to cathodic charge. Its application is at present limited to laboratory cells. The method described is useful for the study of the influence of different parameters such as electrolyte composition, temperature or convection conditions on current efficiency for aluminium deposition.
