LaAl3O6
LaAl3O6 is a metastable, insulating complex oxide that serves as a specialized material within the broader family of spinel oxide catalysts.
About LaAl3O6
LaAl3O6 is a metastable complex oxide that functions as a wide-band-gap insulator. Its structural configuration within the spinel oxide class makes it an intriguing subject for fundamental materials science research, particularly where electronic insulation is required alongside catalytic potential.
Because it exists in a metastable state, this compound offers distinct pathways for structural tuning and synthesis. It serves as a specialized member of the oxide family, providing researchers with a unique electronic profile that contrasts with more common, highly stable catalytic oxides.
Key Properties
Cross-validated computational properties for LaAl3O6, 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 spinel oxide catalysts class.
Unlike the highly stable and widely utilized MgAl2O4 or the conductive perovskite-structured LaNiO3, LaAl3O6 occupies a more niche position in the spinel oxide landscape. While simple binary oxides like NiO or ZnO are frequently employed for their redox properties, LaAl3O6 is defined by its insulating nature, making it a specialized alternative to the more traditional aluminate-based catalysts like Al2O3.
