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.
