Gallium in an Al/Hg reduction
Does anyone here know of any patents or has any experience replacing Hg with Gallium in an Al/Hg reduction. Gallium prevents Al from forming an oxide
layer and can reduce water to form hydrogen, but would it work in the same fasion as Al/Hg and if so, why is it not more widespread since Gallium is
much safer to handle then Hg?

The mercury salt must dissolve the adhering Al oxide as well as inhibit reformation.
Metallic Hg works also albeit very, very slowly.
Will Gallium salts dissolve Al Oxide?

Yes, there is a paper on this effect already. I don't have it handy, but it will work for reductions of -NO2 to NH2 and for several other things.
Neither flask nor beaker.
