Calcium selenite is a stable, insulating inorganic compound composed of calcium, selenium, and oxygen.
About calcium selenite
Calcium selenite is a stable inorganic compound that exists as a wide-gap insulator. Its presence on the thermodynamic convex hull indicates a high level of structural stability, making it a reliable subject for fundamental materials research.
With multiple reported structures across various databases, this compound is well-characterized in the scientific literature. Its insulating nature and stable configuration provide a foundation for understanding the behavior of selenium-based oxoanion systems in solid-state chemistry.
Key Properties
Cross-validated computational properties for calcium selenite, 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
