Stolyarova, S. Lopatin, O. Belousova, L. Grishchenko] The phase equilibria in the Cs2O-B2O3-SiO2 system are investigated in the temperature range 873-1073 K by the annealing-quenching technique, high-temperature microscopy, and X-ray powder diffraction analysis. The vapor composition, the activities of the components, and the Gibbs energies of glasses and melts in the Cs2O-B2O3-SiO2 system are determined at a temperature of 1020 K. It is demonstrated that glasses and melts in the Cs2O · B2O3-Cs2O · SiO2 system are characterized by positive deviations of the CsBO2 activities and negative deviations of the Cs2O · SiO2 activities from ideal behavior. As a consequence, the deviations of the Gibbs energies from ideal behavior change their sign. Pleiades Publishing, Inc., 2006 Stolyarova V.
