CuCuON2

CuCuON₂ is a copper-based ceramic compound containing both metallic copper and oxidized copper species in a nitrogen-containing lattice. This appears to be a research or specialty compound rather than a commercially established material; it likely belongs to the family of copper oxides and nitrides being explored for functional ceramic applications. The mixed-valence copper chemistry and nitrogen incorporation suggest potential applications in catalysis, electrochemistry, or high-temperature service environments where conventional copper oxides prove insufficient.
