在冰晶石-氧化铝熔盐电解中,电解质向阴极渗透以及在阳极上发生阳极效应,这些过程都和电解质对炭电极的湿润性有关系。将近二十年前Жемчужина和Беляев曾在电极极化条件下研究NaF-AlF_3,Na_3AlF_6-Al_2O_3系以及含有盐类添加物的冰晶石熔液在炭板上的湿润角,但试验用电流强度较小(0.01—0.3A)。我们在实验室用微型电解槽,采取较大的电流强度(0.1—5.0A,其中包括与工业上铝电解槽阳极电流密度值
In cryolite-alumina melt electrolysis, the electrolyte penetrates to the cathode and anodic effects occur at the anode, all of which are related to the electrolyte wettability of the carbon electrode. Nearly two decades ago, Жемчужина and Беляев studied the wetting angles of NaF-AlF_3, Na_3AlF_6-Al_2O_3 systems and cryolite solutions containing salt additives on a carbon plate under the condition of electrode polarization. However, the test current intensity was small (0.01-0.3A). We use micro-electrolyzer in the laboratory, take a larger current intensity (0.1-5.0A, including with the industrial aluminum cell anode current density value
