CaTeO3
calcium tellurite
Calcium tellurite is a stable, insulating inorganic compound composed of calcium, tellurium, and oxygen.
About calcium tellurite
Calcium tellurite is a thermodynamically stable ternary oxide that functions as a wide-gap insulator. Its structural integrity on the convex hull makes it a significant subject for researchers investigating the fundamental properties of tellurite-based materials. The compound is characterized by its distinct electronic nature, which limits electrical conductivity and positions it as a potential candidate for specialized optical or dielectric applications. Its structural diversity is highlighted by numerous reported configurations across major materials databases.
Key Properties
Cross-validated computational properties for calcium tellurite, aggregated across 4 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.
