K3Na
K3Na is a metallic intermetallic compound formed from potassium and sodium that is considered a likely candidate for experimental synthesis.
About K3Na
K3Na is a metallic intermetallic compound composed of potassium and sodium. As a metallic system, it lacks a band gap and exhibits characteristic conductive behavior associated with alkali metal alloys. Its electronic structure is dominated by the delocalized valence electrons of its constituent elements.
This compound is notable for its proximity to the thermodynamic hull, suggesting it is a viable candidate for experimental synthesis. With numerous reported structures across multiple databases, it remains a subject of interest for researchers investigating the phase behavior and structural diversity of alkali metal mixtures.
Key Properties
Cross-validated computational properties for K3Na, 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.
