PbCl2-ZnCl2-H2O和CaCl2-PbCl2-H2O三元体系373 K相平衡
Phase equilibria in ternary systems PbCl2-ZnCl2-H2O and CaCl2-PbCl2-H2O at 373 K
摘要
Abstract
In this work, the solubilities of the salt minerals and the densities of solution in two ternary systems of lead chloride-zinc chloride-water and calcium chloride-lead chloride-water were measured at 373 K by using an isothermal solution saturation method. Based on the determined equilibrium solubility data and the corresponding equilibrium solid phase, the phase diagrams and density diagrams of the two systems were plotted. According to the phase diagrams, univariant solubility curves and solid crystalline areas were discussed. The results showed that the two ternary systems were simple without any double salt or solid solution. The phase diagrams of two ternary systems were constituted of one invariant point, two univariant solubility curves and two solid crystalline phase regions. The solid phase was determined by the XRD. And the results of the experiment were simply discussed.关键词
