· JVASP-46838· Na2YPCO7

Na2YPCO7 is an yttrium-based phosphate ceramic compound containing sodium and carbonate species, belonging to the family of rare-earth phosphate ceramics. This material is primarily investigated in research contexts for applications requiring thermal stability and chemical durability, particularly in nuclear waste immobilization, phosphate-based ceramics for radioactive ion capture, and specialized refractory systems. Its significance lies in the ability of rare-earth phosphate frameworks to incorporate and sequester problematic ions, making it relevant for environmental remediation and nuclear materials engineering where conventional oxide ceramics may be less effective.
