· JVASP-20972· Na3ScF6

Na3ScF6 is an inorganic ceramic compound composed of sodium, scandium, and fluorine, belonging to the elpasolite family of fluoride ceramics. This material is primarily of research interest for optical and photonic applications, particularly in laser host materials and solid-state lighting due to its fluoride-based composition, which typically exhibits low phonon energy and good optical transparency. While not yet widely commercialized in mainstream engineering applications, Na3ScF6 and related scandium fluorides are investigated for potential use in mid-infrared optical systems, scintillators, and as precursor materials for advanced ceramic processing, where fluoride ceramics offer advantages over traditional oxides in specialized wavelength ranges.
