· JVASP-50784· Y2Bi2O7

Y2Bi2O7 is a rare-earth bismuth oxide ceramic compound belonging to the pyrochlore family of materials. This material is primarily investigated in research contexts for thermal barrier coating applications and as a potential solid electrolyte in solid oxide fuel cells (SOFCs), where its layered crystal structure and ionic conductivity properties are of interest. Y2Bi2O7 represents an alternative to conventional yttria-stabilized zirconia (YSZ) systems, offering different thermal and chemical stability characteristics that could prove valuable in high-temperature aerospace and energy conversion applications.
