Gallium Metal

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.Ga is avaliable in liquid, solid, granule. 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.

Applications

Gallium element mainly apply to produce semiconductor compounds as gallium arsenidegallium nitridegallium phosphide and so on. It is also dopant for semiconductor germanium wafer, silicon wafer.

Ga element with purity 99.99999% is main raw material for gallium arsenidegallium phosphide and gallium antimonide. Those are for LED and infrared device manufacturing. 8N Ga metal is mainly for preparing superlattice as gallium source of MBE, quantum well and other advanced semiconductor deveices.

High purity gallium liquid metal 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 eutectic alloys as gallium-vanadium, gallium-lithium, gallium-zirconium, gallium-indium-tin(GIS) and so on. Those alloys are as superconductor.  Ga element is essential raw material for low-melting alloys as bismuth alloys, zinc alloys, lead alloys, indium alloys, tin alloys and so on.
