Ba(CuO)2

Ba(CuO)₂ is a barium copper oxide ceramic compound that exists primarily as a research material rather than a commercial engineering ceramic. This mixed-valence oxide falls within the family of high-temperature ceramics and has been investigated for potential applications in superconductivity research, particularly in the context of copper oxide superconductor systems, though it is not itself a superconductor. Engineers and researchers consider this material for fundamental studies of copper oxide phase diagrams, solid-state chemistry, and as a precursor or intermediate compound in synthesis of functional ceramics, rather than as a load-bearing or structural component in conventional applications.
