High-temperature stability of (Gd1−Ce )2Zr2O7+ (x = 0–1) synthesized by spray pyrolysis in air
Source abstract
Abstract
Abstract In this paper, (Gd1−xCex)2Zr2O7+x immobilized matrices with high cerium (Ce) amount-of-substance fractions (up to 90%) were prepared by sol-spray pyrolysis, and then sintered at 1600 °C in air. XRD results showed that all samples were in a mixture of pyrochlore and fluorite phase, even after sintering at 1600 °C. All the sintered bulks were dense, and the densities were independent of the additive content. The SEM results showed that all samples were chemically homogeneous. There was no segregation in the grain boundary. EDS quantification yielded a mean composition close to the stoichiometric chemical composition.
