K4 Sc2 P2 C2 O14

K₄Sc₂P₂C₂O₁₄ is a rare-earth phosphate-based ceramic compound containing scandium, potassium, phosphorus, carbon, and oxygen. This material belongs to the family of complex mixed-metal phosphate ceramics, which are primarily investigated in research settings for their potential in high-temperature applications, ion conductivity, and structural ceramics. While not widely commercialized, scandium-containing phosphate ceramics are of interest for specialized applications requiring thermal stability and chemical inertness in demanding environments.
