Na4 Sc2 P2 C2 O14

Na4Sc2P2C2O14 is a mixed-valence ceramic compound containing sodium, scandium, phosphorus, carbon, and oxygen—a phosphate-based ceramic that belongs to the family of rare-earth and alkaline-earth phosphate materials. This appears to be a research or emerging compound rather than an established commercial ceramic; materials in this chemical family are typically investigated for ion-conduction properties, thermal stability, and potential use in solid electrolytes or luminescent applications. Engineers would consider compounds of this type when exploring advanced ceramics for high-temperature environments, solid-state energy storage, or optical applications where conventional oxides or phosphates fall short.
