The solubility of (KH2PO4 + KCl + H3PO4) at 298.15 K and 308.15 K were determined, using isothermal solution saturation. The equilibrium phase solid was verified by X-ray diffraction (XRD). On the basis of the experimental data, the phase diagrams were plotted. The crystalline regions of KH2PO4 and KCl were determined. The phase equilibrium in different phosphoric acid concentrations are compared and discussed. This comparison further illustrates that the phosphoric acid concentration can influence the equilibrium besides temperatures. All results can offer a fundamental basis for crystallization and separation processes.

系统KH 2 PO 4 + KCl + H 3 PO 4在298.15 K和308.15 K时的相平衡
使用等温溶液饱和度，确定（KH 2 PO 4 + KCl + H 3 PO 4）在298.15 K和308.15 K的溶解度。平衡相固体通过X射线衍射（XRD）验证。根据实验数据，绘制了相图。确定了KH 2 PO 4和KCl的结晶区域。比较和讨论了不同磷酸浓度下的相平衡。该比较进一步说明了磷酸浓度除了影响温度外还可以影响平衡。所有结果均可为结晶和分离过程提供基础。
