US5030427A - Gallium purification - Google Patents

Gallium is purified by washing organic solutions containing hydroxamic acid complexes of gallium with aqueous solutions, individually or in series, especially amine or ammonia solutions, and dilute acid solutions. The method is applicable to a variety of gallium sources, and capable of producing gallium of extremely high purity, especially with a repetitive procedure.

Gallium - an overview | ScienceDirect Topics

The very first report on gallium oxide dates back to 1871, when Dmitri Mendeleev theoretically predicted the existence of a new element, eka-aluminum, and related oxides (Mendeleev, 1871). In 1875 Lecoq de Boisbaudran experimentally isolated a new element, which he named gallium, and described properties of its compounds (De Boisbaudran, 1875).

Gallium - Wikipedia

Gallium is a chemical element with the symbol Ga and atomic number 31. Elemental gallium is a soft, silvery blue 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 ...

Gallium

Gallium is a chemical element with symbol Ga and atomic number 31. It is in group 13 of the periodic table, and thus has similarities to the other metals of the group, aluminium, indium, and thallium. The alloy galinstan (70% gallium, 21.5% indium, and 10% tin) has an even lower melting point of -19 °C, well below the freezing point of water.
