The solubility isotherms of the systems NH4Br - MgBr2 - H2O and NH4Br . MgBr2 . 6 H2O - MgBr2 - H2O have been investigated by the physicochemical analysis method at 75 °C and formation of carnallite type double salt is established. The effect of temperature on the crystallization conditions is discussed.
