K4TiO4
K4TiO4 is a stable, wide-gap insulating oxide that serves as an important structural member of the perovskite-related material class.
About K4TiO4
K4TiO4 is a thermodynamically stable oxide that occupies a distinct position within the perovskite-related family. As a wide-gap insulating material, it exhibits electronic properties characteristic of highly ionic oxide structures, making it a subject of interest for fundamental materials research.
Its stability on the convex hull suggests a robust structural configuration, supported by multiple documented experimental and computational reports. This reliability makes K4TiO4 a valuable reference point for understanding the phase space and chemical bonding trends in alkali-metal-based titanates.
Key Properties
Cross-validated computational properties for K4TiO4, 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 more commonly studied transition-metal perovskites such as BaTiO3 or LaMnO3, which are frequently investigated for their ferroelectric or magnetic properties, K4TiO4 is characterized by its insulating nature and specific alkali-metal stoichiometry. While siblings like LaAlO3 are often utilized as substrate materials, K4TiO4 serves as a unique structural example of how alkali-rich environments influence the stability of titanium-centered oxide frameworks.
