Na4 Tm2 P2 C2 O14

Na₄Tm₂P₂C₂O₁₄ is an inorganic ceramic compound containing sodium, thulium (a rare-earth element), phosphorus, carbon, and oxygen. This material belongs to the family of rare-earth phosphate ceramics, which are primarily of research and developmental interest rather than established commercial products. Rare-earth phosphate ceramics are investigated for high-temperature applications, solid-state ion conductors, and specialized optical or photocatalytic functions, with potential relevance in solid-state batteries, thermal barriers, or advanced refractory systems where rare-earth doping confers specific chemical or thermal stability benefits.
