CdI

Cadmium iodide (CdI₂) is an inorganic ceramic compound belonging to the halide family, typically produced as a crystalline solid with layered crystal structure. It has been investigated primarily for optoelectronic and radiation detection applications, particularly in X-ray and gamma-ray sensing systems where its high atomic number provides effective photon absorption. While not widely deployed in mainstream manufacturing due to cadmium toxicity regulations in many regions, CdI₂ remains of research interest in specialized nuclear instrumentation and high-energy physics detector development, where its scintillation and photoconductive properties offer potential advantages in niche applications requiring direct bandgap semiconducting behavior.
