Аннотация: Abstract: Germanates InFeGe2O7 and GdFeGe2O7 have been produced in the form of polycrystalline powders from stoichiometric mixtures of In2O3 (Gd2O3), Fe2O3, and GeO2 by solid-phase synthesis. Calcination was carried out in air in the temperature range 1273–1473 K. The high-temperature heat capacities of these oxide compounds have been measured using differential scanning calorimetry. The resulting experimental Cp = f(T) data were used to calculate the thermodynamic functions (the enthalpy and entropy changes) of the investigated Fe–In and Fe–Gd germanates. © 2020, Pleiades Publishing, Ltd.
