Gallium — Wikipdia

Le gallium est l'lment chimique de numro atomique 31, de symbole Ga. Il appartient au groupe 13 du tableau priodique ainsi qu' la famille des mtaux pauvres. Le corps simple gallium est un mtal. Sa basse temprature de fusion (29,76 C) lui permet de fondre dans la main. Des traces en sont trouves dans la bauxite et les minerais de zinc.

The abundances of gallium and germanium in terrestrial

Abstract A sensitive spectrophotometric method using phenylfluorone has been applied to the determination of germanium in over 200 minerals, rocks and sediments and in sea water. The crustal abundance of germanium is about 1.7 p.p.m., which is the mean germanium content of both granitic and basic igneous rocks.
