1.Manufacturing semiconductor GaN, GaAs, Gallium phosphide, Ge semiconductor dopants;
2.Pure gallium and low melting alloy can be used as heat exchange medium for Nuclear reaction; Filling material for high-temperature thermometers; It is used as a catalyst for diesterification in Organic reaction.
3.Gallium indium alloys can be used as substitutes for mercury.
Preparation:
It can be extracted from Bauxite or Sphalerite. Finally, pure gallium is obtained through electrolysis.
Mainly recovered and extracted from zinc smelting waste and aluminum smelting waste.
Industrial production uses industrial grade metal gallium as raw material and further purifies it using electrolysis, vacuum distillation, fractional crystallization, and zone melting methods to obtain high-purity gallium. [4] The electrolysis method uses 99.99% industrial grade metal gallium as raw material, and through processes such as electrolytic refining, produces high-purity gallium with a purity of ≥ 99.999%. Using high-purity gallium with a purity of ≥ 99.9999% as raw material, further purification can be achieved by drawing single crystals or other purification processes to obtain high-purity gallium with a purity of ≥ 99.9999%.
