Tungsten · Wolfram
Tungsten is a dense, stable transition metal widely recognized for its superior heat resistance and strength in industrial applications.
About Tungsten
Tungsten is a transition metal characterized by its robust metallic nature and remarkable thermodynamic stability. As an element that sits firmly on the convex hull, it exhibits structural integrity that makes it a foundational material in modern metallurgy and engineering. Its ability to maintain mechanical properties under extreme conditions is a defining feature of its atomic structure. Given its extensive documentation across numerous databases, it remains one of the most thoroughly understood and utilized elements in industrial science. It is primarily valued for its extreme density and resistance to heat, serving as a critical component in high-performance alloys and specialized electrical hardware.
Key Properties
Cross-validated computational properties for Tungsten, 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 W. 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.
