摘要：
Solubilities for the system of MgCl2-MgSO4-MgB4O7-H2O at 298.15 K were calculated by using Pitzer and its extended HW model. The values of the parameters were derived from either literature or through fitting with the solubility data of the relative ternary system in literature. A comparison with the experimental values and calculated solubility data shows that the model can be used successfully to predict the solubilities of the mentioned system. Parameters got in this study can be further used for solubility prediction of more complicated system containing MgB4O7, and the results could provide a theoretical basis for exaction of magnesium borate from salt lake brine resources.
