摘要

Abstract

The germanates CaGd₂Ge₄O₁₂ and CaDy₂Ge₄O₁₂ were synthesized from CaO, Gd₂O₃ (Dy₂O₃), and GeO₂ by the standard ceramic technology. Their crystal structure was refined by X-ray diffraction analysis. The high-temperature heat capacity was measured in the temperature range 320–1000 K using differential scanning calorimetry. Their thermodynamic functions were calculated from the experimental dependences C_p = f(T).
