The fluorite-related “solid solutions” of CeO2 Y2O3 I : A re-examination by electron microscopy and diffraction
“Solid solutions” in the system CeO2Y2O3, originally reported to be continuous and homogeneous and subsequently to consist of two discrete regions of homogeneity, have been re-examined by electron diffraction and high resolution electron microscopy. The two regions of homogeneous solid solution are confirmed and shown to be commensurately modulated structures — based on fluorite type at lower (ab
