摘要
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.
