| Summary: | This paper presents a method for purifying molybdenum concentrate through vacuum distillation and examines the phase evolution of MoS<sub>2</sub> during the process. First, the forms in which impurities exist in molybdenum concentrate and the feasibility of their volatilization are analyzed, while the structural changes of MoS<sub>2</sub> in a vacuum environment are discussed and verified through theoretical calculations. Next, experiments are conducted to study the effects of holding temperature, holding time, and other influencing factors on the transformation process of the molybdenum concentrate. The feasibility of impurity volatilization and the structural evolution of MoS<sub>2</sub> are further evaluated through experimental analysis of the condensates and residues in the temperature interval of 1273–1623 K. The results demonstrate that impurities can be effectively removed without compromising the natural structure of MoS<sub>2</sub>. |
