Abstract
- Oxides Y<subscript>0.65</subscript>Pr<subscript>0.35</subscript>BiGeO<subscript>5</subscript> and Y<subscript>0.65</subscript>Nd<subscript>0.35</subscript>BiGeO<subscript>5</subscript> have been synthesized by a ceramic method. The heat capacity of fine crystalline samples has been studied in the range 350-1000 K by differential scanning calorimetry. The C<subscript>p</subscript> = f(T) dependences can be described by the Maier-Kelley equation. The thermodynamic functions of these oxides—changes in enthalpy, entropy, and reduced Gibbs energy—have been calculated from the experimental data on high-temperature heat capacity.
