Аннотация
Germanate Tb2Ge2O7 has been prepared by solid-phase synthesis from a stoichiometric mixture of Tb2O3 and GeO2 by sequential firing in air at temperatures of 1273–1473 K. The effect of temperature on its molar heat capacity has been studied by differential scanning calorimetry. According to the obtained dependence Cp = f(T), the thermodynamic properties (enthalpy and entropy changes and the reduced Gibbs energy) have been calculated, and the specific heat value at 298 K has been estimated.
