Аннотация: Tb2Sn2O7 has been prepared by solid-state reaction in air at 1473 K over a period of 200 h and its isobaric heat capacity has been studied experimentally in the range 350-1073 K. The C (p)(T) data for this compound have no extrema and are well represented by the classic Maier-Kelley equation. The experimental C (p)(T) data have beeПоказать полностьюn used to evaluate the thermodynamic properties of terbium stannate (pyrochlore structure): enthalpy increment HA degrees(T)-HA degrees(350 K), entropy change SA degrees(T)-SA degrees(350 K), and reduced Gibbs energy DA degrees(D cent).
