详细
The composition and partial pressures of vapor species over the pseudobinary system Al2O3–MgO have been determined by high-temperature mass spectrometry. The data obtained have been used to evaluate the standard enthalpy of formation of nonstoichiometric spinel with the composition MgAl2O4 · 0.793Al2O3 from its constituent oxides by third-law calculations. The entropy of MgAl2O4 · 0.793Al2O3 has been evaluated using a regular-solution model with allowance for cation inversion.
