The cerium-oxygen-carbon system

Wet-etching of precipitation-based thin film microstructures for micro-solid oxide fuel cells

“…It was shown in literature that these residues, i.e. Cl or C, can remain in the material up to high temperatures and incorporate ceria resulting in low packaging densities [23][24][25]. In addition, these chemical residues affect the crystallization and grain growth kinetics through thermal post-annealing of the material [26].…”

Enthalpy and Gibbs energy of formation of cerium dicarbide

“…A tentative ternary diagram for the Ce-O-C system at temperatures below 1873 K has been reported by Clark and McColm [6]. Anderson and Bagshaw [7], have tried to determine the oxygen contamination in the binary cerium/carbon system and to investigate the possibility of oxygen stabilizing a cerium monocarbide phase with a rock-salt type structure.…”
