摘要
Yttrium germanate Y2Ge2O7 was prepared by solid-phase synthesis from a stoichiometric Y2O3–GeO2 mixture under multistage calcination in air within a temperature range of 1273–1473 K. The molar heat capacity of polycrystalline samples was measured by differential scanning calorimetry (DSC), and the CP = f(T) dependence was used to calculate the thermodynamic properties of yttrium digermanates, such as the enthalpy and entropy changes and the reduced Gibbs energy.
