About Potassium aluminate
Potassium aluminate is a robust, thermodynamically stable member of the perovskite oxide family. As a wide-band-gap insulator, it exhibits distinct electronic characteristics that make it a subject of significant interest for structural and dielectric investigations within solid-state chemistry.
This compound is frequently studied for its role in high-temperature ceramic applications and as a precursor in the synthesis of specialized aluminate materials. Its stability on the convex hull underscores its reliability as a building block for complex oxide systems.
Key Properties
Cross-validated computational properties for Potassium aluminate, 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 perovskite oxides class.
Unlike the transition-metal-based perovskites such as LaNiO3 or LaMnO3, which often exhibit complex magnetic or metallic behaviors, KAlO2 is characterized by its stable, insulating electronic structure. It shares more structural commonalities with wide-gap insulators like LaAlO3, serving as a simpler, alkali-metal-containing analog that provides a baseline for understanding the stability of perovskite frameworks.
