Stable Substoichiometric Cerium Oxide Formed in an Air Plasma

W. S. Gilman 1, P. W. Seabaugh 1, and D. B. Sullenger 1

1 Mound Laboratory, Miamisburg, Ohio

Cerium dioxide was reduced to a stable, substoichiometric monophase in an air plasma. This phase has been identified as CeO1.94 by thermal gravimetric analysis. The existence of a stable, reduced phase of cerium oxide can be explained by interpretation of both theoretical and experimentally determined crystal data.
