About Cobalt
Cobalt is a fundamental metallic element recognized for its exceptional thermodynamic stability. As a pure metal, it exhibits characteristic metallic electronic behavior, serving as a critical building block in materials science due to its robust structural integrity and unique magnetic properties.
Its importance spans across heavy industry and high-tech manufacturing, where it is prized for its ability to maintain strength and magnetic performance under demanding conditions. With a vast array of documented structural phases, it remains one of the most extensively studied elements in modern metallurgy.
Key Properties
Cross-validated computational properties for Cobalt, 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 Co. 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.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.
