Mg2Ti
Mg2Ti is a metallic, metastable intermetallic compound formed from magnesium and titanium that is frequently studied for its diverse structural configurations.
About Mg2Ti
Mg2Ti is a metallic binary compound composed of magnesium and titanium. As a metallic system, it lacks a band gap and exhibits conductive properties characteristic of intermetallic phases. Its electronic structure is defined by the interaction between the alkaline earth metal and the transition metal components.
This compound is notable for its complexity in structural studies, appearing in numerous reported configurations across various databases. Because it resides above the thermodynamic hull, it is considered a metastable phase, which makes it a subject of significant interest for researchers investigating phase stability and synthesis pathways in magnesium-based alloys.
Key Properties
Cross-validated computational properties for Mg2Ti, 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.
