Hf3Ta
Hf3Ta is a metallic hafnium-tantalum compound often studied for its structural properties in the context of refractory material research.
About Hf3Ta
Hf3Ta is a metallic compound composed of hafnium and tantalum. As a binary intermetallic, it is characterized by its conductive electronic nature, which is typical for alloys formed between these transition metals.
While this compound appears in multiple structural databases, it is considered thermodynamically metastable. Its existence is often studied in the context of high-temperature alloy development and phase stability in complex refractory systems.
Key Properties
Cross-validated computational properties for Hf3Ta, aggregated across 4 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.
