Gallium - Wikipedia

Gallium is a chemical element with the symbol Ga and atomic number 31. Elemental gallium is a soft, silvery metal at standard temperature and pressure; however in its liquid state it becomes silvery white.If too much force is applied, the gallium may fracture conchoidally.It is in group 13 of the periodic table, and thus has similarities to the other metals of the group, aluminium, indium, and ...

Separation of Gallium from Aluminum Hydroxide ...

The aluminum hydroxide is precipitated out of water, so I'm thinking it'll be easier to discourage the gallium from attaching in solution (if it's actually attached) before we dry it off. I have a meeting in 4 hours to go over some lab experiments we can try, but a lot of these guys have electrical backgrounds and I feel like we're missing some basics .
