摘要：

The enthalpy of formation of lanthanum zirconate, La2Zr2O7, which is shown to have a distorted pyrochlore structure, was determined, High-temperature solution calorimetry in molten lead berate was used to determine the heat of formation from the constituent oxides as -135.8 +/- 6.4 kJ/mol at 974 K. Using additional data on the enthalpies of formation of the oxides and heat contents, this value was converted to a standard enthalpy of formation from the elements: Delta(f)H degrees(298.15) = -4130.4 +/- 6.8 kJ/mol.
