Abstract—
The DyGaTi2O7 and EuGaTi2O7 titanates have been prepared by solid-state reactions in a starting mixture of Dy2O3 (Eu2O3), Ga2O3, and TiO2 via firing in air at temperatures of 1273 and 1573 K, and their crystal structure has been studied by X-ray diffraction. Their high-temperature heat capacity (350–1000 K) has been determined by differential scanning calorimetry. The Cp(T) experimental data have been used to calculate the thermodynamic functions of the titanates.

摘要-
DyGaTi 2 O 7和 EuGaTi 2 O 7钛酸盐是通过在 Dy 2 O 3 (Eu 2 O 3 )、Ga 2 O 3和 TiO 2的起始混合物中通过在空气中在1273 和 1573 K,并通过 X 射线衍射研究了它们的晶体结构。它们的高温热容 (350–1000 K) 已通过差示扫描量热法测定。所述Ç p(Ť)的实验数据已经被用于计算钛酸盐的热力学函数。
