TaTi
TaTi is a metastable metallic compound consisting of tantalum and titanium atoms.
About TaTi
TaTi is a binary metallic compound formed from tantalum and titanium. As a metastable phase, it represents a unique configuration of these transition metals that exists outside of the standard thermodynamic ground state.
Because it exhibits metallic electronic character, this compound is of interest for fundamental studies in metallurgy and alloy science. Its existence across multiple databases highlights its role as a subject of ongoing investigation in materials research.
Key Properties
Cross-validated computational properties for TaTi, 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 TaTi. Tight agreement means computed properties can be trusted without re-running calculations.
