Can the reaction of gallium with aluminium be reversed

Aug 28 Separation membranes hold the key to making hydrogen fuel cheaper in a The gallium layer exclusively allowed hydrogen to pass throughgallium Ga Ga chemical element metal of main Group 13 IIIa or boron its principal spectral lines while examining material separated from zinc blendeGallium reacts with aluminum to form an alloy that is unable to form the tough oxide layer found After all this you will have separated the alloy into its constituent elements which amounts to reversing the reaction I am unable to think of a way
