· JVASP-33806· PmBr3

PmBr₃ (promethium tribromide) is an ionic ceramic compound composed of the rare-earth element promethium and bromine, belonging to the lanthanide halide family. This material is primarily of research and specialized nuclear engineering interest rather than high-volume industrial production, given promethium's radioactive nature and scarcity. Applications are largely confined to nuclear science, radiation shielding studies, and fundamental materials research exploring rare-earth halide properties.
