barium sulfite · barium sulphite
Barium sulfite is a metastable, insulating chemical compound composed of barium, sulfur, and oxygen.
About barium sulfite
Barium sulfite is a chemical compound characterized by its wide-gap insulating electronic structure. As an inorganic salt, it represents a specific arrangement of barium, sulfur, and oxygen atoms that exhibits a metastable thermodynamic profile under ambient conditions.
Because of its distinct electronic nature, this material is of interest for fundamental studies in solid-state chemistry. Its structural diversity is highlighted by the multiple reported configurations found in research databases, reflecting its complex potential for phase behavior.
Key Properties
Cross-validated computational properties for barium sulfite, 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.
