Na3 Mn2 Sb1 O6

Na₃Mn₂SbO₆ is a complex oxide ceramic compound belonging to the pyrochlore or double-perovskite family, combining sodium, manganese, and antimony cations in a mixed-valence oxide lattice. This material is primarily of research interest for energy storage and electrochemical applications, particularly as a potential cathode material for sodium-ion batteries where it offers the advantage of using abundant, low-cost sodium as the charge carrier instead of lithium. The compound's mixed-metal composition and structural framework make it notable for tunable electrochemical properties and thermal stability, though it remains largely in development phases rather than established commercial production.
