Na2 Cu2 O4

Na₂Cu₂O₄ is a layered copper oxide semiconductor compound combining sodium and copper in an ionic oxide structure. This material belongs to the family of mixed-metal oxides and is primarily investigated in research contexts for applications requiring copper-based semiconductive or catalytic properties. Its notable characteristics—including moderate mechanical stiffness and copper's redox activity—position it as a candidate for electrochemical devices, though it remains largely experimental outside specialized research settings.
