Ferrosilite · Iron silicate
FeSiO3 is a semiconducting iron silicate oxide recognized for its potential utility in oxygen-evolution catalysis and electrochemical energy applications.
About Ferrosilite
FeSiO3 is a semiconducting iron-based silicate that belongs to the broader category of oxide oxygen-evolution catalysts. Its structural framework, supported by a significant number of reported configurations, positions it as a material of interest for electrochemical processes where stable, earth-abundant catalysts are required.
As a near-hull material, FeSiO3 is considered a viable candidate for synthesis and experimental validation. Its electronic character and composition make it a distinct subject for researchers aiming to optimize catalytic performance in oxygen-evolution reactions while maintaining thermodynamic robustness.
Key Properties
Cross-validated computational properties for Ferrosilite, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Reported Structures
Lowest-energy structures reported for FeSiO3, ranked by energy above hull.
| Space GroupSymmetry classification of the crystal arrangement. The number is the international space-group index. | Crystal SystemBroad lattice family, such as cubic, tetragonal, monoclinic, or triclinic, derived from unit-cell symmetry. | Band Gap (eV)Electronic gap calculated for this specific reported structure, measured in electronvolts. | E above hull (eV/atom)Thermodynamic distance from the convex hull for this structure, normalized per atom. Lower is generally more stable. | E/atom (eV)Computed total energy normalized per atom. Use energy above hull, not this value alone, when comparing stability. | Density (g/cm³)Mass per relaxed crystal volume, reported in grams per cubic centimeter. |

How It Compares
Within the oxide oxygen-evolution catalysts class.
Within the diverse landscape of oxide catalysts, FeSiO3 offers a unique silicate-based alternative to the more traditional transition metal oxides like NiO or the complex layered structures such as LiCoO2 and LaMnO3. While many of its class members rely on high-valence metal centers for catalytic activity, FeSiO3 leverages its specific iron-silicate coordination to provide a different electronic environment compared to perovskite-type materials like BiFeO3.
