Ca2Sn2O5
Ca2Sn2O5 is a semiconducting calcium stannate oxide that exhibits structural complexity within the perovskite family.
About Ca2Sn2O5
Ca2Sn2O5 is a complex perovskite oxide composed of calcium, tin, and oxygen. As a semiconducting material, it represents an interesting case study in the structural diversity of oxide ceramics, characterized by multiple reported configurations in crystallographic databases. While its thermodynamic status places it above the hull, suggesting potential metastability, it remains a subject of interest for researchers investigating the influence of cation arrangement on electronic behavior in stannate-based perovskites.
Key Properties
Cross-validated computational properties for Ca2Sn2O5, 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.

How It Compares
Within the perovskite oxides class.
Unlike the highly stable and widely utilized BaTiO3 or the robust multiferroic BiFeO3, Ca2Sn2O5 occupies a more precarious position in the perovskite landscape. While materials such as LaFeO3 and LaMnO3 are frequently studied for their magnetic and catalytic properties, Ca2Sn2O5 is distinguished by its tin-based framework, which offers a different electronic environment compared to the transition-metal-heavy siblings like LaNiO3 or LaCoO3.
