HoI3

Holmium iodide (HoI₃) is an inorganic ceramic compound belonging to the rare-earth halide family, composed of the lanthanide element holmium combined with iodine. This material is primarily of research and specialized industrial interest rather than a commodity engineering ceramic, with applications driven by its optical, electronic, and thermal properties characteristic of rare-earth halides. HoI₃ is notable in optics and photonics research for its potential use in laser systems, scintillators, and infrared applications, as well as in specialized catalysis and materials science investigations where rare-earth compounds offer unique reactivity or luminescence properties.
