About YZr5O11
YZr5O11 is a complex oxide belonging to the fluorite-related family of materials. As a semiconducting oxide-ion conductor, it represents a specialized composition within the yttria-zirconia system, characterized by its metastable nature and structural complexity.
This material is of significant interest in solid-state ionics research, where the interplay between oxygen vacancy concentration and crystal structure dictates transport properties. Its unique stoichiometry makes it a subject of study for understanding ion migration pathways in non-equilibrium oxide phases.
Key Properties
Cross-validated computational properties for YZr5O11, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.

How It Compares
Within the fluorite oxide-ion conductors class.
Within the diverse landscape of fluorite-based oxide-ion conductors, YZr5O11 occupies a distinct niche compared to more common pyrochlore-structured phases like Y2Zr2O7 or La2Zr2O7. While many of its siblings rely on highly ordered cation sublattices to facilitate ionic transport, this compound exhibits a different structural arrangement that challenges standard models of conductivity in zirconate-based systems.
