This study investigates the stability of low-temperature aluminum electrolysis, focusing on the significant role of mass transfer processes within the anode-cathode space. Utilizing stationary polarization and voltammetry methods, the research analyzes the kinetics of electrode processes on carbon and metal electrodes within KF-AlF3-Al2O3 melts. The objective was to determine optimal electrolysis parameters while suggesting detailed schemes of the electrode processes based on comprehensive electrochemical tests. The findings reveal crucial insights regarding substance flows in the anode-cathode distance, particularly addressing the factors contributing to the reduction in cathode current efficiency during low-temperature electrolysis in both KF-AlF3-Al2O3 and KF-NaF-AlF3-Al2O3 systems. A critical observation is that cathode current density should remain below 0.4–0.55 A cm−2 at temperatures of 750 °C–800 °C to maintain efficient operation. This research is pivotal in enhancing the understanding of low-temperature electrolysis, which has implications for optimizing aluminum production processes.
