· JVASP-55212· KBiF4

KBiF₄ is an inorganic fluoride ceramic compound belonging to the family of metal fluorides, synthesized primarily for research and specialized optical applications. This material is investigated for use in photonic and laser technologies due to the optical properties characteristic of fluoride ceramics, which can host rare-earth dopants for luminescent and frequency-conversion applications. KBiF₄ represents an emerging compound within advanced functional ceramics rather than a commodity material, and engineers would select it for niche photonic devices where bismuth-containing fluorides offer advantages in transparency and thermal stability over conventional oxides.
