【Abstract】 The object of the experiment research is the brine after low-temperature freeze in Zabuye Salt Lake of Tibet Plateau.According to the quinary metastable phase diagram of 25℃Na +?K +Cl -?SO 2- 4?CO 2- 3,through the process of 20℃normal temperature evaporation,the crystallization law of salts from the brine after different freeze temperatures is studied.At the same time,the evolving rules of the brine composition,brine volume and evaporation rate are obtained.All these provide foundation for the programming and designing of salt fields and directing the production and operation on the spot.更多还原
