· Na4 Cu4 P4 O16

Na₄Cu₄P₄O₁₆ is a mixed-metal phosphate compound combining sodium and copper with a phosphate framework, belonging to the family of inorganic semiconducting ceramics. This is primarily a research-phase material studied for its potential in ion-conduction, energy storage, and photocatalytic applications rather than established industrial use. The copper-phosphate framework combined with sodium mobility makes it of particular interest in battery electrolyte materials and photocatalytic waste-water treatment research, where its semiconductor properties could enable new charge-transport mechanisms compared to conventional oxides.
