About Strontium peroxide
Strontium peroxide is a thermodynamically stable inorganic compound that exists as a solid peroxide. Its electronic character is defined by semiconducting behavior, making it a unique member of the alkaline earth metal peroxide family.
This material is highly valued for its ability to release oxygen under specific conditions and its role in specialized chemical reactions. It is widely utilized in industrial applications where controlled oxidation or specific flame coloration is required.
Key Properties
Cross-validated computational properties for Strontium peroxide, 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.
