High-temperature heat capacity and thermodynamic properties of Tb2Sn2O7

Inorganic Materials Aims and scope

Abstract

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 been used to evaluate the thermodynamic properties of terbium stannate (pyrochlore structure): enthalpy increment H°(T)–H°(350 K), entropy change S°(T)–S°(350 K), and reduced Gibbs energy Ф°(Т).
