Abstract: |
|||
| The present invention provides a precalcined carbon anode used in electrolytic preparation of aluminium. The said carbon anode contains 0.11-1.2% lithium carbonate to attain higher chemical reaction activity and promote anode overvoltage reduction by 120-200 mV and electric current efficiency increase by 1-2%, resulting in electricity saving of 400-600 kw per ton of aluminium produced. | |||
