· CsCu3O2

CsCu₃O₂ is a mixed-valence copper oxide ceramic compound containing cesium and copper in a layered or framework structure. This is primarily a research material studied for its electronic and magnetic properties rather than a conventional engineering ceramic; it belongs to the family of copper oxides that exhibit interesting charge-transfer and potentially superconducting or strongly correlated electron behavior. The compound is of interest in condensed-matter physics and materials chemistry for understanding copper-oxygen coordination chemistry and potential applications in energy storage or quantum materials, though it has not yet achieved widespread industrial adoption.
