SrCa3O4
SrCa3O4 is a metastable, wide-gap insulating ternary oxide containing strontium, calcium, and oxygen.
About SrCa3O4
SrCa3O4 is a complex oxide composed of strontium, calcium, and oxygen. As a wide-gap insulating material, it exhibits electronic properties typical of stable dielectric oxides, though it exists in a metastable state under ambient conditions.
Its structural diversity is highlighted by multiple reported configurations across various databases. This complexity makes it a subject of interest for fundamental studies into phase stability and the synthesis of alkaline earth metal oxides.
Key Properties
Cross-validated computational properties for SrCa3O4, 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.
