摘要: 本文将DCA模型应用于LiF-CaF2,NaF-CaF2和KF-CaF2熔体,并假设在这些熔体中存在络合离子.利用已有的上述混合熔体量热和熔盐相图的实验数据估计了熔体模型中的参数,并计算了熔体的混合热力学参量及相图.计算结果与实验结果吻合较好.

Abstract:The discrete complex anion modle was introduced to the molten salt solutions of LiF-CaF2,NaF-CaF2-and KF-CaF2,based upon the assumption of existence of the CaF3 complex ions contained in the melts.A set of parameters were evaluated from experimental data about enthalpies of mixing and phase diagrams of the above three systems.The thermodynamic properties and phase diagrams of the melts were calculated by using the model.The results obtained were in good agreement with experimental data.Correspondent:XU Qian,(Department of Nonferrous Metallurgy,Northeastern University,Shenyang 110006)
