Nickel is a stable, metallic chemical element widely used as a primary component in alloys and protective coatings due to its durability and conductivity.
About Nickel
Nickel is a fundamental metallic element recognized for its exceptional thermodynamic stability and robust structural integrity. As a pure metal, it serves as a critical building block in materials science, valued for its ability to form stable phases across a wide range of conditions. Its metallic character ensures high electrical and thermal conductivity, making it a cornerstone of modern engineering. With extensive structural data available, it remains one of the most thoroughly characterized elements in the periodic table. Its inherent stability and predictable behavior under various environmental stresses make it an indispensable component in the development of high-performance alloys and protective coatings. By providing a reliable foundation for complex material systems, nickel continues to be a primary focus for researchers aiming to enhance durability and corrosion resistance in demanding applications.
Key Properties
Cross-validated computational properties for Nickel, 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 Ni. 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.
