Chromium is a stable, metallic chemical element widely used to improve the strength and corrosion resistance of alloys and protective coatings.
About Chromium
Chromium is a fundamental metallic element that exists in a highly stable state, making it a cornerstone of modern metallurgy. Its metallic electronic character allows it to form robust bonds, which is essential for its role in creating durable, high-performance materials.
Due to its inherent stability, chromium is extensively utilized to enhance the properties of other metals. It is most recognized for its ability to provide exceptional resistance to oxidation and corrosion, serving as a critical component in the production of stainless steel and various industrial plating applications.
Key Properties
Cross-validated computational properties for Chromium, 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 Cr. 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.
