· Ca2 Cu4 O8

Ca₂Cu₄O₈ is a mixed-valence copper oxide compound belonging to the family of layered perovskite-related ceramics. This material is primarily of research interest for its semiconducting properties and potential applications in superconductivity research, particularly as a precursor or related phase to high-temperature superconducting cuprates. While not yet established in mainstream industrial production, compounds in this family are studied for their electronic transport properties and structural insights into copper-oxide superconductors.
