The solid liquid phase equilibria of reciprocal quaternary system of K+,NH4+//Cl-,H2PO4--H2O and subsystem of KCl-NH4Cl-H2O at 313.15 K were studied by isothermal solution equilibrium method.According to the experimental data,their relevant phase diagrams and the water diagram of the quaternary system and subsystem were drawn.The equilibrium solid phase was identified by wet residue method combined with X-ray diffraction method.The experimental results showed that the ternary system of KCl-NH4Cl-H2O was a partially mutually soluble system,and there were one eutectic point,two univariate curves and five crystallization regions in the phase diagram.Two solid solutions of（K,NH4）Cl and（K,NH4）H2PO4 were formed in the reciprocal quaternary system of K+,NH4+//Cl-,H2PO4--H2O.There were two eutectic points,five univariate curves and four crystallization regions in this quaternary phase diagram.The experimental results could provide necessary basic data for the study of co-crystallization of the system and the corresponding model fitting calculation.
