· Na2 Os4 O12

Na₂Os₄O₁₂ is a mixed-valence metal oxide semiconductor containing sodium, osmium, and oxygen in a complex stoichiometric ratio. This compound belongs to the family of osmium-based oxides and represents a research-phase material studied for its electronic and ionic transport properties rather than a commercially established engineering material. Interest in this compound centers on potential applications in solid-state electrochemistry, oxygen ion conductivity, and advanced ceramic systems, though it remains largely confined to academic investigation rather than established industrial use.
