AlBrO
AlBrO is a thermodynamically stable, wide-gap insulating spinel oxide used in structural and catalytic materials research.
About AlBrO
AlBrO is a distinct member of the spinel oxide catalyst family, characterized by its wide-gap insulating electronic nature. As a thermodynamically stable phase located on the convex hull, it represents a robust structural configuration that maintains integrity under various conditions.
Its significance lies in its structural complexity, with multiple reported configurations across major materials databases. This data richness makes it a valuable candidate for researchers investigating the fundamental properties of insulating oxides in catalytic processes.
Key Properties
Cross-validated computational properties for AlBrO, aggregated across 4 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.

Reported Structures
Lowest-energy structures reported for AlBrO, ranked by energy above hull.
| Space GroupSymmetry classification of the crystal arrangement. The number is the international space-group index. | Crystal SystemBroad lattice family, such as cubic, tetragonal, monoclinic, or triclinic, derived from unit-cell symmetry. | Band Gap (eV)Electronic gap calculated for this specific reported structure, measured in electronvolts. | E above hull (eV/atom)Thermodynamic distance from the convex hull for this structure, normalized per atom. Lower is generally more stable. | E/atom (eV)Computed total energy normalized per atom.

How It Compares
Within the spinel oxide catalysts class.
Unlike the highly conductive or transition-metal-rich members of the spinel class such as LaNiO3 or LaMnO3, AlBrO functions primarily as a wide-gap insulator. While it shares the structural classification of common oxides like MgAl2O4 or Al2O3, its unique elemental composition provides a different chemical environment for potential catalytic applications compared to the more traditional binary oxides like ZnO or NiO.
