· JVASP-102064· K2NaBiF6

K2NaBiF6 is a mixed-metal fluoride ceramic compound containing potassium, sodium, and bismuth. This material belongs to the family of elpasolite and related complex fluoride ceramics, which are primarily investigated for optical and radiation-shielding applications due to bismuth's high atomic number and the transparent or semi-transparent nature of fluoride matrices. Industrial adoption remains limited, with research focus on scintillator materials for radiation detection, potential use in nuclear shielding composites, and specialized optical components where bismuth fluoride compounds offer advantages in X-ray or gamma-ray attenuation compared to conventional ceramics.
