Abstract : Analysis of the conjugate liquid phases in the immiscibility region of the Na2O-B2O3-NaCl system at 830C reveals discontinuities in the trends of solubility of each phase in the other. The discontinuities occur when the proportions of Na2O and B2O3 in the borate phase reach Na2O.5B2O3, Na2O.4B2O3, and Na2O.3B2O3. The solubility behavior is explained in terms of formation of polyborate groups with these compositions, changes in structural ordering at these points, and different equilibria between species in different composition regions.
