| 摘要 |
The invention relates to an electrolytic cell for the production of aluminium by reducing alumina, said cell comprising a sidewall including at least one side block, said side block comprising an aluminous material having an apparent porosity of less than 10% and a composition, as a weight percentage on the basis of the aluminous material and for a total of 100%, such that: Al2O3 > 50%, beta-alumina being less than 20% of the weight of the aluminous material, oxides that are less reducible than alumina at 1000°C < 50%, Na2O < 3.9%, and other components < 5%. |
