A density model based on the Modified Quasichemical Model and applied to the (LiCl plus KCl plus CsCl) liquid

摘要

Differential scanning calorimetry analysis of the various compositions in the (LiCl+CsCl) and (LiCl+KCI+CsCl) systems have been performed, and the composition of 55.5:19.5:25 mol% and 263 C were considered as a eutectic point in the (LiCI+KCI+CsCI) ternary system. A careful evaluation and optimization of our measured phase diagram data and all the other available experimental data for the (LiCI+CsCI) and (LiCI+KCI+CsCI) systems were performed to obtain optimized model parameters for all solid and liquid phases. A thermodynamic data set has been formed and may be used to calculate phase equilibrium and all thermodynamic properties in the (LiCl+KCI+CsCl) ternary system. A density model based on the Modified Quasichemical Model has been employed to evaluate all available density data of the (LiCl+KCI), (KCI+CsCl), (LiCl+CsCl) and (LiCl+KCI+CsCl) melts, and optimized parameters for the density model generated a useful database that can be used to complete a prediction for the density of all liquid phases.
