Abstract
The aspects of structure, dipole ordering, and ionic conductivity of the Na3Cr2(PO4)3 crystal with the four polymorphic phases (α, α', β, and γ) have been investigated. The features of the α-Na3Cr2(PO4)3 crystal structure and its dipole ordering and relaxation polarization in the low-temperature α and α' phases have been refined. The occurrence of Na3Cr2(PO4)3 dipole ordering in the α and α' phases and high ionic conductivity in the β and γ phases is attributed to the structural changes in the rhombohedral [Me2(PO4)3]–33∞ crystal frame upon phase transformations α → α', α' → β, and β → γ. A model for explaining the dipole ordering and ionic conductivity phenomena in Na3Cr2(PO4)3 is proposed.
