摘要
The phase equilibrium and physicochemical properties（density,conductivity and pH value）of the ternary system NaVO3—Na3PO4—H2O were studied at 298 K by the isothermal dissolution method.According to the determined data,the phase diagram and composition-proerties-composition diagram were plotted.The isothermal solubility diagram of the ternary system consists of two univariant curves,one invariant point B,and two crystallization regions for salt Na3 PO>4·8H2O and NaVO3,respectively.No double salt or solid solution is formed.Physicochemical properties（density,conductivity and pH value）regularly change with the composition of solution.
The phase equilibrium and physicochemical properties （density,conductivity and pH value）of the ternary system NaVO3-Na3PO4-H2O were studied at 298 K by the isothermal dissolution method. According to the determined data,the phase diagram and composition - proerties - composition diagram were plotted. The isothermal solubility diagram of the ternary system consists of two univarlant curves, one invariant point B, and two crystallization regions for salt Na2PO 〉 4· 8H2O and NaVO3, respectively. No double salt or solid solution is formed. Physicochemical properties （density, conductivity and pH value）regularly change with the composition of solution.
