Ca3W
Ca3W is a metallic intermetallic compound formed from calcium and tungsten that exhibits complex structural behavior.
About Ca3W
Ca3W is a metallic intermetallic compound composed of calcium and tungsten. Its electronic character is defined by a lack of a band gap, placing it firmly in the metallic regime of materials. The compound exhibits significant structural diversity, as evidenced by its presence across multiple crystallographic databases.
Despite its structural variety, the compound is characterized as being above the thermodynamic hull, suggesting it may be metastable or difficult to synthesize in a pure bulk form. Its existence as a distinct phase remains a subject of interest for researchers studying the complex interactions between alkaline earth metals and transition metals.
Key Properties
Cross-validated computational properties for Ca3W, 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.
