· KCuO2

KCuO₂ is a mixed-valence copper oxide ceramic compound combining potassium and copper in an oxidized phase. This material is primarily of research interest rather than established industrial production, studied for potential applications in catalysis, solid-state electrochemistry, and copper oxide-based functional ceramics. Its notable characteristics stem from copper's variable oxidation states and the structural role of potassium, which may enhance catalytic activity or ionic conductivity compared to simple copper oxides.
