NaTa3O8
NaTa3O8 is a metastable semiconducting perovskite oxide used primarily in advanced materials research.
About NaTa3O8
NaTa3O8 is a semiconducting oxide that belongs to the broader family of perovskite-related materials. As a metastable phase, it represents a complex structural arrangement that is of significant interest for researchers studying phase stability and electronic behavior in transition metal oxides. Its unique composition highlights the diverse structural possibilities within the tantalum-based oxide landscape. Because of its electronic character, this compound serves as a valuable subject for investigating charge transport and light-matter interactions in non-equilibrium states. It is primarily utilized in fundamental materials research where the exploration of metastable phases can unlock new pathways for functional oxide design.
Key Properties
Cross-validated computational properties for NaTa3O8, 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.
Within the diverse class of perovskite oxides, NaTa3O8 occupies a distinct niche compared to more common, thermodynamically stable members like BaTiO3 or LaAlO3. While materials such as LaMnO3 and LaFeO3 are frequently studied for their magnetic and catalytic properties, NaTa3O8 is characterized by its metastable nature, which sets it apart from the highly stable, well-characterized perovskites that dominate industrial applications.
