Li＋,Na＋∥,CO32－,B4O72－-H2O 四元交互体系288 K的相平衡
摘要:
采用等温溶解平衡法对Li＋,Na＋∥,CO32－,B4O72－-H2O四元体系进行288 K相平衡研究.结果表明,该体系属简单共饱型，在288 K等温溶解度相图中有二个共饱点，五条单变量曲线，平衡固相为Na2CO3•10H2O， Li2B4O7•3H2O，Na2B4O7•10H2O, Li2CO3.

Equilibrium Phase Diagram of Li＋,Na＋∥,CO32－,B4O72－-H2O Quaternary System at 288 K
Abstract:
In this paper, the solubility of Li＋,Na＋∥,CO32－,B4O72－-H2O quaternary system at 288 K has been determined by isothermal equilibrium method. Based on the solubility data, the phase diagram of the system has also been plotted, in which there are two invariant point E and F(see Fig.1)， five univariant curves E1F, E2F, E3E, E4E and EF, and four crystallization fields: Na2CO3•10H2O，Li2B4O7•3H2O，Na2B4O7•10H2O, Li2CO3.
