Description
Thermodynamic data from room temperature to the melting point have been obtained for Sr2P2O7, Ba2P2O7 and Ra2P2O7: the isobaric heat capacity (Ср), changes in the enthalpy (НТ‒H298), the entropy (ST‒S298), the Gibbs energy (ФТ‒Ф298) functions. For this purpose the Kellogg‒Kubaschewski method, the Neumann‒Kopp method, classical thermodynamic expressions were used. The obtained thermodynamic data can be reused to determine other properties, in particular thermochemical ones: enthalpy and Gibbs energy of formation, equilibrium constant of formation reactions of Sr2P2O7, Ba2P2O7, and Ra2P2O7.
