High purity gallium metal is mainly used for synthesis of GaAs, GaN, GaP, and other low melting point alloy base material. It is widely used in communications, electronics and national defense industry. In recent years, a substantial increase in the demand for the high purity gallium metal emerged, the expansion of market capacity increased quickly. Therefore, it is necessary to analyze the research progress on the high-purity gallium crystallization technology, so as to further promote the development of related technologies. The theoretical basis was summarized, and the research status of the part crystallization method, the directional crystallization method, the zone melting method and the crystal pulling method and compared their inherent advantages and disadvantages were analyzed. In the conclusion part, it was proposed that the coupling of the crystallization method and the other processing purification method was an important research direction on the research for the purification of crude gallium metal.
