Niobium · Columbium
Niobium is a stable, superconducting transition metal widely used to enhance the strength and performance of high-temperature alloys and medical devices.
About Niobium
Niobium is a lustrous, grey transition metal that exhibits robust thermodynamic stability. As a metallic element, it is characterized by its excellent ductility and ability to form protective oxide layers, making it a cornerstone material in high-performance metallurgy.
Its importance stems from its unique electronic properties, which include a transition into a superconducting state at low temperatures. These characteristics make it indispensable for demanding industrial applications where structural integrity and electrical efficiency are paramount.
Key Properties
Cross-validated computational properties for Niobium, 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 Nb. 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.
