ARRANGEMENT OF ANODE FOR UTILISATION IN AN ELECTROLYSIS CELL |
摘要 |
The invention relates to an arrangement of anode for utilisation in an electrolysis cell for production of aluminium metal from an aluminium containing component in a molten salt electrolyte, in which the aluminium containing component mainly is alumina and the molten salt electrolyte is based on mixtures of NaF and AIF3 and CaF2, and possibly alkaline and alkali ne earth halides. More specific it relates to improvements of anodes useful for retrofit of existing electrolysis cells, in which the anodes remains inert during operation. The anode is characterised by being shaped in a manner to increase the area of the electroactive surface. Several examples of such designs are shown. The anode is useful for utilisation in retrofit of existi ng electrolysis cells of Hall-Hèroult design for aluminium production.
