The isothermal dissolution equilibrium method was used to determine the solubilities of salts and the equilibrium solid phases in the two ternary systems: Li2SO4–Li2B4O7–H2O and K2B4O7–K2SO4–H2O at 273 K. These results are also used to construct phase diagrams of the two ternary systems. Both phase diagrams have an eutectic point, two univariant solubility curves, and two crystallization regions of single solid phase. At the eutectic point of the ternary system Li2SO4–Li2B4O7–H2O, the coexisting solid phases are Li2B4O7·3H2O and Li2SO4·H2O; at the eutectic point of the ternary system K2B4O7–K2SO4–H2O, the coexisting solid phases are K2B4O7·4H2O and K2SO4.

两个三元系统的相平衡：273 K时的Li 2 SO 4 –Li 2 B 4 O 7 –H 2 O和K 2 B 4 O 7 –K 2 SO 4 –H 2 O
等温溶解平衡法用于确定两个三元系统中的盐的溶解度和平衡固相：Li 2 SO 4 –Li 2 B 4 O 7 –H 2 O和K 2 B 4 O 7 –K 2 SO 4 -H 2 ö在273K这些结果也用于将两个三元体系的构建体相图。两个相图都有一个共晶点，两个单变量溶解度曲线和一个固相的两个结晶区域。在三元体系的共晶点处，Li 2 SO 4 –Li2 B 4 O 7 –H 2 O，共存的固相为Li 2 B 4 O 7 ·3H 2 O和Li 2 SO 4 ·H 2 O；在三元体系K 2 B 4 O 7 -K 2 SO 4 -H 2 O的共晶点处，共存固相为K 2 B 4 O 7 ·4H 2 O和K 2 SO 4。
