Structural phase transition, equation of state and phase diagram of functional rare earth sesquioxide ceramics (Eu_1-xLa_x)₂O₃.

ABSTRACT: The intriguing functional nature of ceramics containing rare earth sesquioxide (RES) is associated with the type of polymorphic structure they crystallize into. They prefer to be in the cubic, monoclinic or hexagonal structure in the increasing order of cation size, R_RE. Since the functional properties of these ceramics varies with R_RE, temperature and pressure, a systematic investigation delineating the cation size effect is indispensable. In the present work we report the structural stability and compressibility behaviour of the RES ceramics, (Eu_1-xLa_x)₂O₃, of RESs with dissimilar structure and significant difference in cationic radii. The selected compositions of (Eu_1-xLa_x)₂O₃ h
