| 摘 要： | 采用等温溶解平衡法研究了288 K时K2B4O7-L i2B4O7-MgB4O7-H2O四元体系的相平衡关系,测定了平衡液相的等温溶解度和密度。研究发现：该体系属于简单共饱和体系,无复盐和固溶体生成;该四元体系288 K时的等温溶解度图存在三个固相结晶区,其平衡固相分别为：Li2B4O7.3H2O,K2B4O7.4H2O和MgB4O7.9H2O;一个共饱点E,三条单变量曲线E1-E,E2-E,E3-E;文章最后对实验结果进行了简单讨论。

| Abstract: | The solubilities and densities of the quaternary system of K2B4O7-Li2B4O7-MgB4O7-H2O at 288 K were studied by isothermal equilibrium method. The system belongs to a simple co - saturated system, and no - salt and sdid solution generation. Based on the solubility data, the metastable equilibriumphase diagram of the system was plotted, which consists of one invariant point E; three univariant curves E1 - E, E2 - E, and E3 - E, three crystallization fields Li2B4O7.3H2O,K2B4O7.4H2O and MgB4O7.9H2O. The results of properties in the solution were discussed briefly. |
