This paper presents experimontal data of the metastable equilibrium for pentanary system of (Na+、K+、Mg2+),(Cl-、SO42-), H2O, from which the metastable phase diagram is mado.It consists of eight regions of crystallization (all saturated with sodium chloride):potassium chloride, glasserit (3K2SO4·MgSO4),schoenite (K2SO4·6H2O),sodium,sulfate, astrankit (MgSO4·Na2SO4·4H2O),magnesium sulfate septahydrate, carnallite (KCl·MgCl2·6H2O),and bischofit (KCl·MgSO4·6H2O).It is also proved than the metastable equilibrium exists in polynary system.
