氟碳铈矿热分解动力学研究

Study on Thermal Decomposition Kinetics of Bastnaesite

采用Harcourt Esson方法对不同来源的氟碳铈矿晶体热分解动力学进行了系统研究,得到的反应机制方程用普适积分法进一步验证,结果显示微山矿热分解为一级反应,不同品位的冕宁、非洲、芒廷帕斯氟碳铈矿热分解反应都是按照三维扩散机制进行的。

The kinetics parameters describing the thermal decomposition of different Bastnaesite were obtained by the HarcourtEsson method and were verified by the universal integral. The results show that the decomposition mechanism of the ore from Weishan is the oneorder reaction, but that of Mianning, Africa and Mountain Pass is based on threedimensional diffusion.
