Abstract

Vaporization and thermodynamic properties of the SrO–Al2O3–SiO2 system are studied by high-temperature differential mass spectrometry in the concentration range from 90 to 10 mol % of SrO and the molar ratio of x(Al2O3)/x(SiO2) = 1.5. The samples are evaporated from Knudsen effusion cell made of tungsten. The partial pressures of the molecular forms of the vapor, the activities of the condensed phase components, the Gibbs energies, and the excess Gibbs energies are determined. It is established that the studied system is characterized by a slight negative deviation from the ideal behavior. For mullite (Al6Si2O13) the value of the standard enthalpy of formation is determined. The melting points of the synthesized samples are established by high-temperature microscopy.
