Abstract (en)
Method for adding traces of sodium to a melt (2) of aluminium or an aluminium alloy, characterized in that an electrode (3) is immersed in the melt (2) which contains molten sodium or a molten sodium compound (5) which is separated from the melt (2) by a solid-state electrolyte (7) conducting sodium ions, and by providing a direct voltage between said electrode (3) and the melt (2). <IMAGE>
