Mg3W
Mg3W is a metallic magnesium-tungsten compound characterized by significant structural diversity despite its metastable nature.
About Mg3W
Mg3W is a metallic intermetallic compound composed of magnesium and tungsten. As a metallic system, it exhibits characteristic electronic behavior associated with its elemental constituents, though it is currently understood to exist in a metastable state relative to its ground-state phases. Despite its thermodynamic instability, the compound is of significant interest in computational materials science due to the high number of structural configurations reported across multiple databases. This structural diversity highlights the complex bonding landscape between magnesium and tungsten.
Key Properties
Cross-validated computational properties for Mg3W, 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.
