Na4 Y2 P2 C2 O14

Na₄Y₂P₂C₂O₁₄ is a mixed-metal phosphate-carbonate ceramic compound combining sodium, yttrium, phosphorus, and carbon oxides into a complex crystal structure. This is primarily a research-phase material studied for its potential in solid-state ion conductivity and thermal management applications, rather than a widely commercialized engineering ceramic. The material family of rare-earth phosphate ceramics shows promise for high-temperature applications and specialized electrochemical systems where conventional ceramics fall short.
