· JVASP-9317· YFeW2O8

YFeW2O8 is a mixed-metal oxide ceramic composed of yttrium, iron, and tungsten elements. This compound belongs to the family of rare-earth iron tungstates, which are primarily investigated for functional ceramic applications rather than structural use. The material is largely in the research domain, with potential applications in magnetic ceramics, high-temperature dielectrics, and specialized optical or catalytic systems where the combination of rare-earth and transition-metal oxides provides unique electronic or magnetic behavior.
