Abstract
Phase formation in the LaPO4–YPO4–(H2O) system have been studied under hydrothermal conditions at T ~ 230°C and after heat treatment in air in the temperature range 1000–1400°C. The phase equilibria diagram in the system has been constructed for the LaPO4–YPO4 system. The regions of metastable binodal and spinodal decomposition of a phase with a monazite structure with a critical point Tcr = 931°C have been calculated. The experimentally determined eutectic temperature of 1850 ± 35°C is in good agreement with the calculated value Te = 1820°C. The maximum solubility of YPO4 in LaPO4 at eutectic temperature obtained from the results of thermodynamic optimization of the phase diagram is 50.5 mol %.
LaPO4-YPO4-(H2O) 体系中的相图和易变相
摘要 在T ~ 230°C的水热条件下以及在1000-1400°C温度范围内的空气中进行热处理后，对LaPO4-YPO4-(H2O)体系中的相形成进行了研究。为 LaPO4-YPO4 体系构建了体系中的相平衡图。计算了具有临界点 Tcr = 931°C 的独居石结构相的可转移双晶和旋光分解区域。实验测定的共晶温度为 1850 ± 35°C，与计算值 Te = 1820°C 非常吻合。根据相图的热力学优化结果，在共晶温度下，YPO4 在 LaPO4 中的最大溶解度为 50.5 摩尔%。
