Key Properties
Cross-validated computational properties for Na5TaO5, 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.

How It Compares
Within the perovskite oxides class.
Unlike the widely utilized ferroelectric BaTiO3 or the magnetic perovskites like LaMnO3 and LaFeO3, Na5TaO5 is characterized by its alkali-rich stoichiometry. While many members of this class, such as LaAlO3, are primarily studied for their dielectric or catalytic properties, Na5TaO5 provides a distinct structural perspective within the broader perovskite oxide landscape.
