Moreno，Kresak和Zahradnik(1977)测定的羟基磷灰石(OHA)、氟磷灰石(FA)及其部分固溶体的溶解度数据被解释为准二元组分OHA和FA的活度。一些固溶体显示FA的活度远大于1。用规则固溶体和亚规则固溶体混合型模型对实验数据进行了解释。相互作用参数W的最佳值为11.7kJ·−~(-1)。红外光谱研究结果证实了该模型，表明F-OH-F和F-OH构型的重要性。
Solubility data determined by Moreno, Kresak, and Zahradnik (1977) on hydroxyapatite (OHA), fluoroapatite (FA) and some of their solid solutions were interpreted in terms of the activities of the quasibinary components OHA and FA. Some solid solutions showed activities for FA considerably larger than unity. The data were explained with the model of a mixed‐type regular and subregular solid solution. The best value for the interaction parameterWis 11.7 kJ mol−1. The model is corroborated by the results of IR studies which indicate the importance of F — OH — F and F — OH configurations.
