· CdO2

CdO2 is an inorganic ceramic compound based on cadmium oxide, belonging to the family of metal oxide ceramics. This material is primarily of research and specialized industrial interest, valued for its electronic and optical properties in applications requiring high refractive index or semiconductor behavior. While cadmium compounds have historical use in pigments, coatings, and photovoltaic research, CdO2 specifically is investigated in advanced materials research for potential applications in optoelectronics and thin-film technologies, though its practical deployment remains limited compared to less toxic alternative oxides.
