· JVASP-14187· Na2Cu3Ge4O12

Na2Cu3Ge4O12 is a quaternary oxide ceramic compound combining sodium, copper, and germanium in a mixed-metal oxide framework. This material is primarily of research interest rather than established industrial production, investigated for potential applications in ion-conducting ceramics and solid-state electronic devices where the copper and germanium oxide components may offer interesting electrochemical or photonic properties.
