· JVASP-44467· Y2W2O9

Y2W2O9 is a mixed rare-earth tungstate ceramic compound combining yttrium and tungsten oxides. This material belongs to the family of tungstate ceramics, which are of significant interest in high-temperature and specialized optical applications due to their thermal stability and potential for hosting rare-earth ions. While primarily a research compound rather than a widely commercialized engineering material, Y2W2O9 and related tungstate systems are investigated for luminescent, thermal barrier, and nuclear fuel applications where conventional oxides face performance limitations.
