摘要：
The solution enthalpy of SrLaGaO4 in the 2PbO.B2O3 melt at 973 K was measured using a high-temperature Calvet microcalorimeter. The enthalpies of formation of SrLaGaO4 from the constituent oxides and constituent elements were determined to be -96.8 +/- 5.9 and -2128.7 +/- 6.1 kT/mol, respectively. The partial pressures of the vapor species over molten SrLaGaO4 at T-m = 1793 K were evaluated. The equilibrium oxygen pressure at 1793 K was found to be 4.13 x 10(-2) Pa.
