· JVASP-19041· Y2Sn2O7

Y2Sn2O7 is a pyrochlore-structured ceramic compound composed of yttrium, tin, and oxygen. This material belongs to the family of rare-earth tin oxides and is primarily investigated in research contexts for its potential as a thermal barrier coating, ion conductor, and radiation-resistant ceramic due to the pyrochlore structure's inherent disorder tolerance and thermal stability. It represents an emerging candidate material for advanced aerospace and nuclear applications where conventional ceramics show performance limitations.
