ceramic

· JVASP-25021· K5AuI2O2

K5AuI2O2 is an experimental mixed-metal oxide ceramic containing potassium, gold, and iodine elements. This compound belongs to the family of complex metal oxides and halides, currently known primarily through materials research rather than established industrial production. The material's potential applications lie in specialized ceramics research, particularly for studies involving gold-containing oxides in electronic, photonic, or catalytic contexts where the unique combination of noble metal (Au) and halide components might offer novel functionality.
