MgMnSiO4
MgMnSiO4 is a stable, insulating silicate compound known for its diverse structural configurations.
About MgMnSiO4
MgMnSiO4 is a complex silicate compound characterized by its insulating electronic nature and robust thermodynamic stability. As a member of the silicate family, it sits securely on the convex hull, indicating a highly favorable energetic state that makes it a significant subject for structural analysis.
Its structural versatility is evidenced by multiple reported configurations across various databases. This diversity in atomic arrangement highlights its importance in understanding phase transitions and stability within complex mineral-like systems.
Key Properties
Cross-validated computational properties for MgMnSiO4, 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.

Reported Structures
Lowest-energy structures reported for MgMnSiO4, 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. |
