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.

BaO-Al2O3-SiO2体系熔体的气相形成及热力学性质

采用高温差质谱法研究了BaO - Al2O3 - SiO2体系在90 ~ 10 mol % BaO和x(Al2O3): y（SiO2）的摩尔比分别为3:2、1:1和1:2的条件下熔体的蒸发过程和热力学性质。样品从由钨制成的克努森积液池中蒸发。测定了气态组分的分压、缩合相组分的活度、吉布斯能和过量吉布斯能。确定了所研究的系统具有与理想行为负偏差的特征。
