Abstract: This paper summarizes the research results of vacuum distillation of Pb-Sb alloy and crude antimony. In our study, we have found the basic law which states that in Pb-Sb phase diagrams, the part which is rich in lead can be used to guide the purification of lead by distillation, while the part rich in antimony can be used to guide the purification of Sb, where the compositional point C is the azeotropic mixture. The technical experimental results at temperatures between 700-850℃ are coincident with those of theorical study. The expanding experiment at the 100kg scale produced satisfactory results.
