| Abstract: | The thermodynamics of the reaction of Y 2O 3 with HF gas wse calculated.Activity energy E of the fluoridation reaction wsa obtained through the dynamic experiments.The effects of time and temperature on the fluoridation have been investigated.The products of the fluoridation of Y 2O 3 have also been studied by XRD method.The mechanism of fluoridation was discussed to offer the theoretical basis for the technology of producing rare earth fluoride with high quality. |
