摘要：
Dy2Ce2O7 ceramic material was prepared by solid reaction method at 1600 A degrees C for 10 h. The phase composition, microstructure, and thermal conductivity of this material were investigated. XRD results reveal that single-phase Dy2Ce2O7 with fluorite structure was synthesized successfully. Microstructure of Dy2Ce2O7 was dense and no other unreacted oxides or interphase existed in the interfaces between grains. Because of phonon scattering by oxygen vacancies and difference in atomic mass between substitutional atoms and host atoms, thermal conductivity of Dy2Ce2O7 is lower than that of 8YSZ, which implies that this ceramic can be used as novel candidate materials for thermal barrier coatings in the future.
