引言熔融氯化物电解时,金属铝和阳极上析出的氯之间的二次反应始终被认为是造成电流效率损失的重要因素。乌克谢(Ukshe)等哈利沃德(Hallioday)和姆赛因托什(mcintosh)曾指出,从含氯化镁的熔体中电解镁时,二次反应的程度主要是受电解槽几何形状和氯气泡所引起的熔体运动的影响。由于设计想法相似,这些考虑也将应用到氯化铝电解槽上,所以,对于氯气泡与熔体和阴极产品之间行将发生的相互作用加深了解,将会有助于选择最适宜的 Introduction During the electrolysis of molten chloride, the secondary reaction between metal aluminum and chlorine precipitated on the anode has always been considered as an important factor in the loss of current efficiency. Hallioday and McIntosh, Ukshe et al., Have pointed out that the extent of secondary reactions when electrolyzing magnesium from a melt containing magnesium chloride is mainly determined by cell geometry and Effect of chlorine bubble on melt movement. Because of the similar design considerations, these considerations will also apply to aluminum chloride electrolyzers, so a better understanding of the interactions that will occur between chlorine bubbles and melt and cathode products will help to select the most appropriate
