The aim of this study is to clarify a growth process of an image crystal. A shape of cavity formed in a sintered CeO (IV)sample was examined by FE-SEM. It was confirmed that image crystal was formed in the sample sintered under reduced atmosphere.

Polyhedral cavities which is called image crystal were observed in the Cerium Oxide sample sintered under reducing atmosphere. The facet became clear with decreasing O/M ratio which facilitates the atomic diffusion rate. This result suggests that the atomic diffusion rate of matrix significantly affects the formation of the image crystals.
