Lithium fluoride · LiF
Lithium fluoride is a stable, insulating salt used primarily for its exceptional optical transparency and resistance to radiation.
About Lithium fluoride
Lithium fluoride is a simple binary salt that exists as a thermodynamically stable crystal. It is characterized by a wide band gap, classifying it as a highly effective electrical insulator with significant optical transparency across a broad spectrum.
This material is widely utilized in specialized technical fields, particularly where high-energy radiation or ultraviolet light transmission is required. Its structural stability and electronic insulating behavior make it a fundamental component in advanced optical coatings and molten salt reactor technology.
Key Properties
Cross-validated computational properties for Lithium 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.
