· InBr3

Indium tribromide (InBr₃) is an inorganic ceramic compound belonging to the III-V halide family, consisting of indium and bromine in a 1:3 stoichiometric ratio. This material is primarily of research and developmental interest rather than established in high-volume industrial production, with potential applications in optoelectronics, semiconductors, and layered material systems where halide perovskites and their precursors are explored. InBr₃ is notable in materials science as a precursor or component for emerging technologies in thin-film optics, solid-state devices, and two-dimensional material engineering where its layered crystal structure and halide chemistry offer tunable properties for next-generation semiconductors and photovoltaic systems.
