Key Properties
Cross-validated computational properties for Mg3FeO4, 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 oxide oxygen-evolution catalysts class.
Unlike the highly conductive or metallic-like behavior often seen in transition-metal-rich oxides such as LaNiO3 or LaMnO3, Mg3FeO4 is defined by its insulating character. While it shares the oxide framework common to materials like LiCoO2 or BiFeO3, its distinct composition positions it as a specialized candidate for catalytic research where wide-gap electronic properties are advantageous.
