| Abstract: | This paper reports the experimental data of metastable phase equilibrium of K2CO3-KCl-H2Oternary system at 298K for Zhabuye salt lake in Tibet from which the metastable phase diagram was plotted.The results indicate that his ternary system is a simple-eutectic-type one,no double salt or solid solution was found.Tow metastable solubility curves of the system correspond to tow the crystallization fields of K2CO3 3/2H2Oand KCl salts.It is found in the metastable equilibrium phase diagram that: the crystallizat... |
