Abstract：The electrolysis of chlorides is an important method to prepare rare earth metals and alloys by molten salt electrolysis method. The relevant information on the complex ions in the molten salts can be obtained by the high-temperature Raman spectroscopy so as to guide the production practice. This paper introduced the principle of Raman spectroscopy and its advantages in high temperature detection. The research results of Raman spectroscopy in rare earth chloride systems in the literature were emphatically described. Finally, the prospect for future research of Raman spectroscopy in the field of molten chloride system for electrolysis preparation of rare earth metals and their alloys was put forward.
