High-purity antimony (Sb) is essential for industries like semiconductors and photovoltaics, driving research on its production. This review summarizes research advances in production and preparation techniques for high-purity Sb. Three process flowcharts to produce high-purity Sb are described according to different raw materials. Various process parameters of vacuum distillation, zone refining purification techniques and research progress in the field of high-purity Sb are discussed. Numerical simulation, atomic scale simulation, and research progress of alloying elements in the field of high-purity Sb are highlighted. It is shown that for the difficult removal of As element in Sb, the addition of Al makes the regional refining process more effective in reducing the arsenic content. Finally, the purification of high-purity Sb is summarized, providing insights into achieving efficient and environmentally friendly high-purity Sb production and outlining future directions.
