About BaNb2O6
BaNb2O6 is a thermodynamically stable member of the perovskite oxide family, characterized by its wide-gap insulating electronic profile. Its structural integrity and consistent formation across multiple databases highlight its significance as a robust candidate for fundamental materials science investigations.
As a stable oxide, this compound serves as a platform for studying dielectric and structural properties in complex ceramic systems. Its reliance on the interplay between barium and niobium cations makes it a valuable material for exploring high-performance electronic applications.
Key Properties
Cross-validated computational properties for BaNb2O6, aggregated across 4 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 conductive or magnetic members of the perovskite class such as LaNiO3 or LaMnO3, BaNb2O6 functions primarily as a stable insulator. While materials like BaTiO3 are widely utilized for their ferroelectric properties, BaNb2O6 is distinguished by its specific structural stability and insulating nature, positioning it differently within the broader landscape of functional oxides.
