摘　　要：ＣａＯ－Ｐ２Ｏ３－Ｈ２Ｏ体系的相平衡王越郭志琴陈嘉甫（四川联合大学西区化工系，成都６１００６５）关键词亚磷酸相平衡活度系数１前言有关资料指出［１～３］，亚磷酸氢钙（ＣａＨＰＯ３）是一种优良的防锈颜料。其防锈性能好，而且无毒，无公害。此外，它也可以用...A part of phase equilibrium data of CaOP_2O_3H_2O system at 25℃ and 40℃ were tested by the method of isothermal solubility. Based on Pitzer′s electrolyte solution theory, an activity coefficient model for the relative components in the system was set up. The parameters of the model were calculated by optimizing the experimental data at 25℃. The result showed a good coherence between the experimental data and those of calculating with this model.
