Impact of sintering parameters on the microstructure of homogeneous U1‐xCexO2+δ ceramics

open access: yesJournal of the American Ceramic Society, Volume 108, Issue 5, May 2025.
Abstract The effects of atmosphere and cerium content on the densification and the final microstructure of homogeneous U1‐xCexO2+δ solid solutions (x = 0.10; 0.25; 0.50) were investigated. Dilatometric studies first revealed that while the cerium content only slightly modifies sintering under an Ar/H2 atmosphere, a change of the gas to argon ...
