ceramic

· JVASP-57380· KNaMnO2

KNaMnO₂ is a mixed-metal oxide ceramic compound containing potassium, sodium, and manganese in an oxide matrix, representing a ternary alkaline-earth transition metal oxide system. This material belongs to the family of layered or tunnel-structured metal oxides, which are primarily investigated in research contexts for electrochemical energy storage and catalytic applications rather than as a commodity engineering ceramic. The potassium-sodium-manganese oxide composition is notable for potential use in lithium-ion battery cathode materials, oxygen reduction catalysts, and environmental remediation applications, where the mixed valency and structural flexibility of manganese oxides can be exploited.
