作为研究四元体系Ｎａ２Ｂ４Ｏ７－Ｎａ２ＣＯ３－ＮａＨＣＯ３－ＮａＢＯ２－Ｈ２Ｏ的开端，测定了三元体系Ｎａ２Ｂ４Ｏ７－ＮａＨＣＯ３－Ｈ２Ｏ和Ｎａ２ＣＯ３－ＮａＢＯＨ２－Ｈ２Ｏ在０℃、１５℃－４５℃时的溶解度，绘制了相应的组成－性质图。两个三元体系的溶度图在研究温度范围内均属于低共饱型，平衡固相为组分化合物或其水合物。
The solubility of Na2B4O7-NaHCO3-H2O and Na2CO3-NaBOH2-H2O in the ternary system of Na2B4O7-Na2CO3-NaHCO3-NaBO2-H2O was determined at 0 ℃ and 15 ℃ -45 ℃. The corresponding solubility Composition - Nature Map. The solubility diagrams of the two ternary systems all belong to the low cosotential type in the study temperature range. The equilibrium solid phase is the component compound or its hydrate.
