· JVASP-12502· Pr2Br5

Pr2Br5 is a rare-earth halide ceramic compound composed of praseodymium and bromine, belonging to the family of lanthanide bromides that are primarily investigated in advanced materials research rather than established commercial production. This layered halide structure is of interest in materials science for potential applications in solid-state ionics, optical devices, and emerging electronic applications where rare-earth halides show promise due to their unique crystal structures and ionic properties. The material remains largely experimental, with its development driven by fundamental research into halide perovskites and rare-earth ceramic families that could enable next-generation technologies in energy storage and photonics.
