Application of a linear enthalpy relationship to crystalline perovskite phases (MTiO 3)

The titanium-based oxides (MTiO 3), with perovskite structure, are gaining more and more attention due to its promising applications in gas detection, non-linear optics, nuclear waste treatment and so forth. Thermodynamic properties of MTiO 3 are needed for assessing their behavior. In this letter,...

Summary:The titanium-based oxides (MTiO 3), with perovskite structure, are gaining more and more attention due to its promising applications in gas detection, non-linear optics, nuclear waste treatment and so forth. Thermodynamic properties of MTiO 3 are needed for assessing their behavior. In this letter, a linear enthalpy correlation, developed from the Sverjensky–Molling linear free energy relationship has been used to calculate the standard enthalpy of formation of the particular crystalline perovskite phases from the known thermodynamic properties of the corresponding aqueous divalent cations (M 2+). Using the linear enthalpy relationship, the standard enthalpies of formation of various MTiO 3 are calculated. This linear enthalpy correlation may provide a useful tool for predicting unknown thermodynamic properties from a limited number of available data.
