MgTa
MgTa is a metallic magnesium-tantalum intermetallic compound that is thermodynamically unstable.
About MgTa
MgTa is a metallic intermetallic compound composed of magnesium and tantalum. As a metallic phase, it exhibits characteristic electrical conductivity associated with its electronic structure, reflecting the interaction between the alkaline earth metal and the refractory transition metal.
Despite its existence in a high volume of reported structural configurations across various databases, the compound is characterized as being thermodynamically unstable relative to its constituent elements. Its presence in structural records highlights the complex phase space of magnesium-tantalum alloys.
Key Properties
Cross-validated computational properties for MgTa, 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.
