Key Properties
Cross-validated computational properties for rhodonite, 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 and widely utilized LiNiO2 or LaNiO3, MnSiO3 offers a different electronic profile that challenges conventional design strategies for oxygen-evolution catalysts. While many of its class members like LiMn2O4 are optimized for battery applications, MnSiO3 serves as a specialized silicate-based oxide that provides a unique structural framework for exploring catalytic activity in oxygen-evolving environments.
