Abstract
Zone refining was applied experimentally to high-purity aluminium produced by a combination of the three-layer electrolytic refining process and the segregation process. The cropping procedure was effective in increasing the efficiency of zone refining. The highest residual resistance ratio R(300K)/R(4.2K) obtained was more than 150 000 in the bulk value, corresponding to a refined purity better than 99.99999 %.
