Gallium is a widely distributed element associated with many other minerals but, since it is not found in concentrated deposits, it is rarely mined directly. Gallium is primarily obtained as a by-product in the recovery of other metals such as zinc and aluminum. Its chemical behavior is similar to aluminum. In general there is a thin oxide coating on the surface.

Gallium

It is stable against water, but can react vigorously with halogens (even at low temperatures) and other strong oxidants and bases.

With its very low melting point and high boiling point, Gallium has the longest liquid range of any element. It also has a strong tendency to supercool below its freezing point. Gallium expands 3.1% upon freezing, so it should not be stored in glass or metal containers as they may break when the metal solidifies. The main use for gallium is in the manufacture of semiconductor compounds. Gallium also finds numerous applications in the production of eutectic alloys (often used as a substitute for mercury) and in coatings of glasses and mirrors. Small quantities of metallic gallium are used for special dental alloys.
