Abstract: In this paper, the solubilities of the title systems and its sub-systems of the Na2B4O7-K2B4O7-H2Oat 25℃ are presented. Meanwhile, the solubility parameters at binary and ternary co-saturated points are given and the dry-salt diagram and water diagram of the four-component systems are also shown.
