Аннотация: Gd2Sn2O7 gadolinium stannate with the pyrochlore structure has been prepared by solid-state reaction and its high-temperature heat capacity has been determined by differential scanning calorimetry in the temperature range 350-1020 K. The C (p) (T) data are shown to be well represented by the classic Maier-Kelley equation. The experПоказать полностьюimental C (p) (T) data have been used to evaluate the thermodynamic functions of gadolinium stannate: enthalpy increment HA degrees(T)-HA degrees(339 K), entropy change SA degrees(T)-SA degrees(339 K), and reduced Gibbs energy Dcurrency signA degrees(T).
