SrSO4
Celestine · Celestite, Strontium sulfate
SrSO4 is a stable, insulating strontium sulfate mineral widely recognized for its structural consistency and geological abundance.
About Celestine
SrSO4 is a robust, thermodynamically stable inorganic compound that exists as a wide-gap insulator. Its structural integrity is underscored by its presence on the convex hull, reflecting a highly favorable energetic state that supports its prevalence in geological and synthetic contexts.
Due to its insulating nature and stability, this compound is frequently studied for its diverse structural arrangements. With numerous documented configurations across multiple databases, it serves as a foundational reference point for understanding sulfate-based material systems.
Key Properties
Cross-validated computational properties for Celestine, 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.
