Abstract
The processes of vaporization and thermodynamic properties of melts of the BaO–Al2O3–SiO2 system are studied using the method of high-temperature differential mass spectrometry in the concentration range from 90 to 10 mol % BaO and molar ratio of x(Al2O3) : y(SiO2), equal to 3 : 2, 1 : 1, and 1 : 2. The samples are evaporated from Knudsen effusion cells made of tungsten. The partial pressures of gaseous species, activities of condensed phase components, Gibbs energies, and excess Gibbs energies are determined. It is established that the studied system is characterized by a negative deviation from ideal behavior.
