Abstract
Molten salt electrolysis is used for the preparation of metal with high purity in a one-step procedure. When dealing with metal sulfides, a modified FFC (replacing oxides with sulfides) process shall prevent the emission of sulfur oxides if a protective atmosphere is provided. In this paper, the chemical stability of MoS2 in chloride eutectic molten salt system (NaCl–KCl, CaCl2–KCl, CsCl–KCl, and LiCl–KCl) was studied to explore the reaction mechanism of MoS2 in molten salt. Moreover, the influence of adding K2S was also investigated. MoS2 tablets were immersed into the molten salt for 8 h and the SEM graph of the samples was observed focusing on the boundary between the tablet and solid salt. MoS2 powder was also used to investigate existence of the intermediate product by XRD through the same process. The solubility of MoS2 in each molten salt system was also determined.
