Gallium metal is silvery white minor metal, which is liquid when temperature above 29℃, but solid when temperature under it. It is also soft even when solid. Liquid gallium tends to undercool that mean it would’t solidify even temperature under 0℃. It slightly dissolve in mercury and form gallium amalgam. Liquid gallium can infiltrate glass, so it cannot use glass container to store.

Gallium metal mainly apply to produce semiconductor compounds as gallium arsenide, gallium nitride, gallium phosphide and so on. It is also dopant for semiconductor germanium, silicon.
99.99999% Ga is main raw material for gallium arsenide, gallium phosphide and gallium antimonide. Those are for LED and infrared device manufacturing. 8N Ga is mainly for preparing superlattice as gallium source of MBE, quantum well and other advanced semiconductor deveices.
High purity gallium can be as additive for permanent magnet material and other alloys. It is also raw material for high purity alloys.
Liquid gallium is raw material for gallium alloys as gallium-vanadium, gallium-lithium, gallium-zirconium and so on. Those alloys are as superconductor. It is also essential raw material for low-melting alloys as bismuth alloys, zinc alloys, lead alloys and so on.
