摘要
Ternary oxide GdBiGeO5 was synthesized by a ceramic method. The heat capacity of crystalline gadolinium bismuth germanate as a function of temperature in the range 373-1000 K has been studied by differential scanning calorimetry. It has been demonstrated that the temperature dependence of the heat capacity can be described by the classical Maier-Kelley equation. From the experimental C (P) = f(T) data, the thermodynamic functions (the change in enthalpy and entropy) of ternary oxide GdBiGeO5 have been calculated.
