Manganese · alpha-manganese
Manganese is a stable, metallic chemical element widely used as a critical alloying agent to improve the strength and durability of steel and other materials.
About Manganese
Manganese is a fundamental metallic element known for its remarkable structural complexity. It exists as a thermodynamically stable phase, sitting firmly on the convex hull, which underscores its importance as a building block in inorganic chemistry and materials science.
Due to its electronic character as a metal, it is widely utilized for its ability to modify the properties of alloys. Its high degree of structural variety, evidenced by numerous reported experimental configurations, makes it a subject of extensive study for researchers aiming to optimize its performance in various industrial environments.
Key Properties
Cross-validated computational properties for Manganese, aggregated across 5 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.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of Mn. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
