Gallium Arsenide Industrial Grade 99.99%

Gallium arsenide is crystal of cubic crystal system, which is an important semiconductor material. It is available in pieces, ingots, rods, powders and wafers. It stable and don’t corrode by non-oxidizing acid under 600℃.GaAs could process into semi-insulating material that is triple electrical resistivity than silicon and germanium, which is for integrated circuit substrate and infrared detector. However it would decompose at high temperature, so the technique is complex to get ideal high purity monocrystal GaAs. Gallium metal and arsenic metal are the raw material.

Gallium Metal Industrial Grade 99.99%

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.
