摘要：
The La2Ce2O7 powder doped with Sr was synthesized by sol-gel method in this study and its dense bulk samples were also prepared by pressureless-sintered at 1600 degrees C for 10h. Its phase composition, microstructure, and thermophysical property were investigated. Results reveal that pure (La0.95Sr0.05)(2)Ce2O6.95 with single fluorite structure was successfully synthesized. Microstructure of bulk sample is dense. Its thermal expansion coefficient is higher than that of Y2O3-stabilized ZrO2 (YSZ) and its thermal conductivity is lower than that of YSZ. These results show that (La0.95Sr0.05)(2)Ce2O6.95 ceramic can be explored as the candidate material for thermal barrier coatings.
