With numerous reported structures across major databases, this compound serves as a well-documented example of tin-based perovskite chemistry. Its stability and predictable behavior under various conditions allow it to function as a reliable precursor and functional material in inorganic synthesis.
Key Properties
Cross-validated computational properties for Sodium stannate, 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.
While many perovskite oxides like LaNiO3 or BaTiO3 are widely recognized for their complex magnetic or ferroelectric behaviors, Na2SnO3 is distinguished by its role as a stable, semiconducting stannate. Unlike the transition-metal-heavy perovskites such as LaMnO3 or BiFeO3, which often exhibit strong electronic correlations, this compound provides a more chemically robust framework that is frequently utilized in industrial applications requiring consistent material properties.
