摘要
本文对Ｙ２Ｏ３与无水ＨＦ气体的反应过程进行了热力学计算，并根据实验结果，计算了该反应在３００～７００℃的活化能，研究了氟化反应时间、温度等因素对氟化反应的影响，同时对氟化产物进行了Ｘ射线衍射分析，探讨了氟化反应过程的机理，为合理确定制备高质量稀土氟化物的工艺条件提供了理论依据。
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.
