摘要
采用等温溶解平衡法研究了三元体系Li2SO4-Li2B4O7-H2O在323.15 K时的溶解度及其平衡溶液的密度、pH性质,根据实验数据绘制了相应的平衡相图及其物化性质组成图。研究结果表明:该三元体系在323.15 K时有2个结晶相区(Li2B4O7.3H2O和Li2SO4.H2O)、2条单变量溶解度曲线、1个共饱点,属简单共饱型。
Solubilities and solution properties （density, pH） of the ternary system Li2SO4-Li2B4O7-H2O at 323.15 K were studied by isothermal solution equilibrium method, and the equilibrium phase diagram and the composition diagram physieochemieal properties were plotted based on this experimental data. The experimental phase diagram shows that there are two univariant curves, one invariant point and two crystallization fields corresponding to Li2B4O7.3H2O and Li2SO4 . H2O in the ternary system Li2SO4-Li2B4O7-H2O at 323. 15 K, and it belongs to the simplified type of co - saturated ternary system obviously.
