· Na8 Co4 O12

Na8Co4O12 is a mixed-valence sodium cobalt oxide ceramic compound belonging to the family of layered perovskite-related oxides. This is a research-phase material currently studied for its electronic and ionic transport properties rather than established industrial production. The compound is of interest in solid-state ionics and thermoelectric applications where sodium-ion mobility and transition metal redox behavior can be leveraged; it represents an alternative compositional space to conventional lithium-based oxide ceramics, with potential relevance to emerging sodium-ion energy storage systems and high-temperature electrochemical devices.
