Tantalum is a dense, ductile, and highly corrosion-resistant transition metal used extensively in electronics and chemical processing equipment.
About Tantalum
Tantalum is a transition metal characterized by its robust metallic nature and remarkable thermodynamic stability. As a highly reliable material, it remains on the convex hull, indicating its inherent structural integrity under standard conditions.
Its unique physical properties make it indispensable for high-performance engineering. Because it is chemically inert and maintains structural consistency, it is widely utilized in environments where durability and resistance to degradation are paramount.
Key Properties
Cross-validated computational properties for Tantalum, 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 Ta. Tight agreement means computed properties can be trusted without re-running calculations.
