· JVASP-33830· LuBr3

Lutetium tribromide (LuBr₃) is an inorganic ceramic compound belonging to the rare-earth halide family, combining lutetium—the densest lanthanide element—with bromine in a 1:3 stoichiometric ratio. This material is primarily encountered in research and specialized applications where rare-earth halides are valued for their optical, thermal, or chemical properties; industrial adoption remains limited compared to more common ceramics. LuBr₃ is investigated in contexts such as scintillation detector development, high-temperature chemistry, and materials science research exploring rare-earth halide performance, though it is not a mainstream engineering material for general structural or thermal applications.
