Gallium also has a slightly larger surface water residence time than aluminium. [110] Gallium has a similar dissolved profile similar to that of aluminium, due to this gallium can be used as a tracer for aluminium. [110] Gallium can also be used as a tracer of aeolian inputs of iron. [111]
Perey discovered it as a decay product of 227 Ac. [177] Francium was the last element to be discovered in nature, rather than synthesized in the lab, although four of the "synthetic" elements that were discovered later (plutonium, neptunium, astatine, and promethium) were eventually found in trace amounts in nature as well.

The Pentagon holds a strategic stockpile for germanium but currently has no inventory reserves for gallium, a spokesperson said on Thursday, after China announced export restrictions on the two ...
The chemical elements were discovered in identified minerals and with the help of the identified elements the mineral crystal structure could be described. One milestone was the discovery of the geometrical law of crystallization by René Just Haüy , a further development of the work by Nicolas Steno and Jean-Baptiste L. Romé de l'Isle (the ...
China on Tuesday banned exports to the United States of the critical minerals gallium, germanium and antimony that have widespread military applications, escalating trade tensions the day after ...
Bauxite is the main source of the rare metal gallium. [17] During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ion-exchange resin. [18]
