Experimental determination and thermodynamic optimization of the LiF-NdF system.

Neodymium is mainly obtained by electrolysis of a molten LiF-NdF-NdO system. LiF-NdF is a basic system, and the phase diagram of this system provides important information in the production of electrolytic neodymium. An accurate LiF-NdF binary phase diagram helps in the selection of the appropriate molten salt component in production and optimizing the production process, which is of great significance to improve the electrolysis efficiency and reduce the production cost.
