About K3NO4
K3NO4 is a complex inorganic compound composed of potassium, nitrogen, and oxygen. It is characterized as a wide-band-gap insulator, indicating that it does not readily conduct electricity under standard conditions.
This material is notable for its thermodynamic stability, as it sits on the convex hull of its constituent elements. With multiple reported structures across various databases, it represents an interesting subject for structural studies in solid-state chemistry.
Key Properties
Cross-validated computational properties for K3NO4, aggregated across 3 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.
