· JVASP-18501· NdI2

Neodymium diiodide (NdI₂) is an ionic ceramic compound belonging to the rare-earth halide family, characterized by layered crystal structure typical of lanthanide dihalides. This material is primarily of research interest rather than established commercial use, being investigated for potential applications in layered material systems, optoelectronics, and solid-state chemistry where rare-earth halides are explored for their unique electronic and structural properties. The layered nature of NdI₂ makes it a candidate for exfoliation-based applications and heterostructure engineering in advanced materials research.
