Abstract—Optimal conditions for the synthesis of Sm₂Sn₂O₇ with pyrochlore crystal structure by solid-phase reactions were determined. The effect of temperature (346–1050 K) on the molar heat capacity of samarium stannate was studied by differential scanning calorimetry. Thermodynamic properties of Sm₂Sn₂O₇ in the temperature range under study were determined using the experimental data.
