| Abstract: |
| The relationship between alumina concentration and alumina decomposition voltage, bath voltage, bubble voltage, reaction overvoltage and diffusion overvoltage of anode were theoretically analyzed. The relationship between cell voltage and alumina concentration was determined and the R–C curve was plotted. This study provides a theoretical principle for alumina concentration control in aluminum electrolysis. |
