摘　　要：本文在实验室条件下研究了铝电解中掺杂Ｌｉ、Ｌｉ＋Ｂａ、Ｍｇ＋Ｆｅ盐的石墨电极对阳极反应的电催化作用，发现这些掺杂电极能显著降低炭阳极反应的过电压。工业应用表明。该项技术给自焙铝电解槽带来了巨大的节能增产效益。The electrocatalysis of anodic reaction was studied by doping Li,Li+Ba,Mg+Fe salts into the graphite anode in laborato-ry,reduce the anodic overvoltage in Hall-Her-oult process,The industrial application showsthat a remarkable power saving and increasingproduction were obtained by using this tech-nology in Soderberg cells.A new field to re-duce energy was also found in high tempera-ture electroltsis.
