ceramic

· JVASP-21407· K2NaInF6

K2NaInF6 is a complex fluoride ceramic compound containing potassium, sodium, indium, and fluorine. This material belongs to the family of inorganic fluoride ceramics, which are primarily investigated in research contexts for optical and electronic applications where high chemical stability and specific refractive properties are valuable. While not yet widely established in mainstream engineering practice, fluoride ceramics of this type show promise in specialized optical windows, laser host materials, and advanced electronic device applications where corrosion resistance and thermal stability are critical.
