gallium | Uses, Properties, & Facts | Britannica

Though widely distributed at Earth's surface, gallium does not occur free or concentrated in independent minerals, except for gallite, CuGaS 2, rare and economically insignificant.It is extracted as a by-product from zinc blende, iron pyrites, bauxite, and germanite. Gallium is silvery white and soft enough to be cut with a knife.

Gallium citrate ga-67 | C6H5GaO7 - PubChem

Gallium Citrate Ga-67 is the citrate salt of the radioisotope gallium Ga 67. Although the mechanism is unknown, gallium Ga 67 concentrates in lysosomes and is bound to a soluble intracellular protein in certain viable primary and metastatic tumors and focal sites of inflammation, allowing scintigraphic localization. Ga-67 scintigraphy (GS) cannot differentiate between tumor …
