Er_2Ge_2O_7–Er_2Sn_2O_7 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 Er_2Ge_2O_7 thermodynamic functions have been calculated.
