· JVASP-57777· KCaF3

KCaF3 is a fluoride-based ceramic compound belonging to the perovskite family, synthesized as a research material for optical and structural applications. While not widely commercialized, it is investigated for use in optical crystals, fluoride glass systems, and as a host material for rare-earth ion doping in photonics research. Its fluoride composition offers potential advantages in transparency across infrared wavelengths and chemical stability, making it relevant for emerging photonic and laser applications where traditional oxides face limitations.
