| Popis: | Thermodynamic properties of binary alkali borate systems Me2O–B2O3 have been studied in the framework of sub-regular solution theory approximation. The oscillation method of phase analysis was used to obtain precise data for solid–liquid equilibria. A non-monotonic correlation function for these properties (the melting temperature and entropy of melting, the exchange energy for infinitely dilute solution of a metal oxide in the melt of boron oxide) and the alkali ionic radii of borate compounds nMe2O·mB2O3 is suggested. It is found as a first approximation that a melt supercooling grows when a compound dissociation degree rises. |
