ceramic

· JVASP-59062· Pb7Br2F12

Pb₇Br₂F₁₂ is a mixed halide ceramic compound combining lead with bromine and fluorine, belonging to the family of halide perovskites and related framework structures. This material is primarily of research interest for optoelectronic and photonic applications, where the combination of lead halides offers potential for tunable bandgap properties and ionic conductivity. While not yet established in high-volume industrial production, compounds in this family are being investigated for solid-state electrolytes, scintillators, and radiation detection—areas where the high atomic number of lead and the tunability of halide frameworks offer advantages over conventional oxide ceramics.
