This paper presents the experimental data of metastable phase equilibrium of Na+, K+, Mg2+∥Cl-, SO2-4-H2O quinary system at 35 ℃, from which the metastable phase diagram is drawn. It consists of nine regions of crystallization saturated with sodium chloride, potassium chloride, glasserite(3K2SO4*Na2SO4), leonite(K2SO4*MgSO4*4H2O), kainite(KCl*MgSO4*2.75H2O), thenardite(Na2SO4), astrankit(MgSO4*Na2SO4*4H2O), carnallite(KCl* MgCl2*6H2O), magnesium sulfate hexahydrite(MgSO4*6H2O) and bischofit(MgCl2*6H2O).
