Ca1 Cd1 O2

Cadmium oxide (CdO) is an inorganic semiconductor compound belonging to the II-VI semiconductor family, characterized by a rock salt crystal structure. While cadmium oxide has historical use in applications requiring transparent conductive coatings and as a component in specialty glasses and ceramics, its industrial adoption has been significantly limited by cadmium's toxicity and environmental concerns; research interest persists primarily in optoelectronic devices and thin-film applications where its wide bandgap and electrical properties remain theoretically useful, though safer alternatives are increasingly preferred for production applications.
