Title: High-Temperature Specific Heat of the TmBiGeO{sub 5} and YbBiGeO{sub 5} Compounds

Abstract

The TmBiGeO{sub 5} and YbBiGeO{sub 5} compounds have been synthesized from Tm{sub 2}O{sub 3} (Yb{sub 2}O{sub 3}), Bi{sub 2}O{sub 3}, and GeO{sub 2} oxides by the solid-state synthesis with successive burning at 1003, 1073, 1123, 1143, 1173, and 1223 K. High-temperature specific heat of the oxide compounds has been measured by differential scanning calorimetry. Basing on the experimental dependences C{sub p} = f(T), the thermodynamic properties of the oxide compounds, i.e., the enthalpy and entropy variations, have been calculated.
