· JVASP-74763· KBeBr2

KBeBr₂ is an inorganic ceramic compound combining potassium, beryllium, and bromine elements. This material belongs to the halide ceramic family and is primarily of research and specialized optical interest rather than commodity industrial use. It is investigated for potential applications in infrared optics and scintillation detection systems, where its crystal structure and optical transparency properties may offer advantages in wavelength ranges where common glass or oxide ceramics have limitations.
