Occurrence, isolation & synthesis

Greyish metal with a greenish-blue reflection [6].


In nature, gallium is found in the Earth's crust, 5 ppm, in zinc blende and aluminum clay as well as ores of iron, chromium and manganese [6]. The isotopes found in nature are 69Ga (60.2 %, stable) and 71Ga (39.8 %, stable) [6].

In pure solid form, gallium exist in a orthorhombic structure [2].
