Cr5Sb3O16
Cr5Sb3O16 is a semiconducting, metastable oxide material that belongs to the broader family of spinel-related catalysts.
About Cr5Sb3O16
Cr5Sb3O16 is a complex semiconducting oxide belonging to the spinel-related family. Its unique composition of chromium and antimony suggests potential for specialized catalytic activity, though it is characterized as a metastable phase located above the thermodynamic hull.
Due to its structural complexity, this compound is primarily of interest in fundamental materials research. It serves as an example of the diverse phase space within antimony-doped chromium oxides, where electronic properties are tuned by specific elemental arrangements.
Key Properties
Cross-validated computational properties for Cr5Sb3O16, 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.
