The enthalpy of solution of SrLaA1O4 in the 2PbO · B2O3 melt at 973 K was measured using a hightemperature Cal vet microcalorimeter. The enthalpies of formation of SrLaA1O4 from the constituent oxides and constituent elements at 298.15 K were determined to be -97.7 ±5.5 and -2422.9 ±5.6 kJ/mol, respectively. The partial pressures of the vapor species over molten SrLaA1O4 at Tm = 1923 K were evaluated. The equilibrium oxygen pressure at 1923 K was found to be 5.05 × 10-3 Pa.
