Na6 O6 P2 S2

Na₆O₆P₂S₂ is an inorganic ceramic compound combining sodium, phosphorus, sulfur, and oxygen—a rare mixed-anion phosphate-sulfate system. This is primarily a research-phase material studied for its potential in solid-state ion conductivity and electrochemical applications, rather than an established commercial ceramic. Interest in this compound family stems from the investigation of alternative solid electrolytes and ionic conductors for next-generation batteries and electrochemical devices, where the mixed phosphate-sulfate framework may offer unique transport properties or thermal stability characteristics.
