摘要

在 2-1825 K 的温度范围内测量了热长石钆钛酸盐 Gd2Ti2O7 的等压热容。热力学函数（熵、焓变、还原吉布斯能）是利用热容量的一致平滑值计算得出的。估计了高温范围内由氧化物形成 Gd2Ti2O7 的吉布斯能。

Thermodynamic Properties of Gadolinium Titanate Gd2Ti2O7

The isobaric heat capacity of pyrochlore gadolinium titanate Gd₂Ti₂O₇ is measured in the 2–1825 K range of temperatures. Thermodynamic functions (entropy, enthalpy change, reduced Gibbs energy) are calculated using consistent smoothed values of heat capacity. The Gibbs energy of the formation of Gd₂Ti₂O₇ from oxides in the high temperature range is estimated.
