CrBiO3
CrBiO3 is a semiconducting ternary oxide catalyst that is theoretically stable enough to be synthesized for specialized chemical applications.
About CrBiO3
CrBiO3 is a semiconducting oxide that belongs to the broader class of spinel-related catalysts. Its electronic character and structural configuration make it an intriguing candidate for advanced chemical processes where precise surface reactivity is required.
Because it sits near the thermodynamic hull, CrBiO3 is considered a viable target for synthesis. With multiple reported crystal structures, it represents a flexible material platform for researchers investigating the intersection of bismuth and chromium chemistry in catalytic applications.
Key Properties
Cross-validated computational properties for CrBiO3, 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.
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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Reported Structures

| 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 stable and widely utilized MgAl2O4 or the simple binary oxides like NiO and ZnO, CrBiO3 offers a more complex ternary framework. While perovskite-structured siblings like LaMnO3 or LaNiO3 are often prioritized for their specific magnetic and electronic properties, CrBiO3 provides a unique compositional alternative for catalytic pathways that require the specific redox potential of chromium integrated with bismuth.
