Progress of Technology on Preparing High Purity Gallium

Gallium with high purity is mainly used in electronic and communication industry in the form of GaAs, GaP, GaN and low melt point alloy. The application of gallium with high purity becomes wider and the need for it increases steadly. The paper reviews the method of manufacturing high purity gallium, with emphasis on electrolysis refining, partial crystallization, electrolysis crystallization, vacuum rectification, vacuum thermal decomposition and so on, and proposes that it is essential to enhance the research and production of high purity gallium in our country.
