直到不久前,才掌握了有关熔盐电解质与非极化液态铝界面上相间表面张力σ_(12)的试验数据。根据这些数据可以认为,阴极金属界面上电解质的表面活性愈小,金属的损失就愈少;相应地,电流效率亦愈大。因此,为降 Until recently, experimental data on the interfacial surface tension σ_ (12) between the molten salt electrolyte and the unpolarized liquid aluminum interface were obtained. Based on these data, it can be considered that the smaller the surface activity of the electrolyte on the cathode metal interface, the less metal loss; accordingly, the greater the current efficiency. Therefore, to drop
