NaF
Sodium fluoride · Villiaumite
Sodium fluoride is a stable, insulating salt widely recognized for its role as a fundamental alkali halide in chemical research and industrial applications.
About Sodium fluoride
Sodium fluoride is a simple inorganic salt composed of sodium and fluorine. It is characterized as a wide-gap insulator that exhibits exceptional thermodynamic stability, consistently appearing on the convex hull of its constituent elements.
Due to its robust chemical nature and structural simplicity, this compound is a highly studied material with extensive documentation across numerous crystallographic databases. Its stability and electronic properties make it a foundational reference point in the study of alkali halides.
Key Properties
Cross-validated computational properties for Sodium fluoride, 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.
