摘要：

Titanate GdGaTi2O7 has been obtained from the initial oxides Gd2O3, Ga2O3, and TiO2 by the solid-state synthesis via annealing in air at temperatures of 1273 and 1573 K. The crystal structure of the titanate has been refined by X-ray diffraction. The high-temperature (320-1000 K) heat capacity of the compound has been measured by differential scanning calorimetry. Based on the experimental dependence C-p = f(T), the main thermodynamic functions of the titanate have been calculated.
