· JVASP-38115· Rb2NaInF6

Rb2NaInF6 is a mixed-metal fluoride ceramic belonging to the elpasolite family of ionic compounds, characterized by a face-centered cubic crystal structure containing rubidium, sodium, indium, and fluorine. This material is primarily investigated in research contexts for optical and scintillation applications, where its fluoride composition offers transparency in the ultraviolet to visible spectrum and potential as a host matrix for rare-earth dopants. The double-perovskite fluoride structure makes it notable compared to oxide ceramics for applications requiring chemical stability against moisture and high refractive index contrast, though it remains largely a laboratory compound rather than a mature industrial material.
