Abstract
The compounds DyInGe2O7 and HoInGe2O7 were synthesized by multistage calcination of stoichiometric mixtures of the constituent oxides (solid-phase synthesis) in air in the temperature range 1273–1473 K. The high-temperature heat capacities of polycrystalline samples of dysprosium–indium and holmium–indium mixed-cation germanates were measured by differential scanning calorimetry. The thermodynamic properties of the investigated oxides were calculated using the Cp = f(T) experimental data.
