Abstract

Er₂Ge₂O₇–Er₂Sn₂O₇ solid solutions have been obtained using solid-state synthesis by burning the stoichiometric mixtures of the initial oxides in air in the temperature range of 1273–1473 K. The effects of temperature and solid solution composition on the specific heat have been examined by differential scanning calorimetry. The Er₂Ge₂O₇ thermodynamic functions have been calculated.
