Thermodynamic Calculations and Experiments for Preparation of Neodymium Fluoride with Hydrogen Fluoride

In this paper,it is introduced the thermodynamic calculations for reaction process of preparing neodymium fluoride with hydrofluoric acid,and it is studied the influences of major factors such as time and temperature,etc.of fluorination on the rate of fluorination,which provide evidences of theory and practice for producing neodymium fluoride.
