LuTaO4
Lutetium tantalate · Lutetium orthotantalate
Lutetium tantalate is a stable, insulating oxide widely utilized as a high-density phosphor host in X-ray imaging technology.
About Lutetium tantalate
Lutetium tantalate is a robust, thermodynamically stable inorganic oxide that functions as a wide-gap insulator. Its structural integrity and electronic properties make it a highly reliable material for demanding optical and sensing environments.
Because it sits firmly on the convex hull, this compound exhibits excellent chemical and thermal stability. These characteristics are essential for its role in high-performance applications where material longevity and consistent performance under radiation are critical.
Key Properties
Cross-validated computational properties for Lutetium tantalate, 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.
