· JVASP-37598· Yb3Y

Yb₃Y is a rare-earth ceramic compound composed of ytterbium and yttrium oxides, belonging to the family of rare-earth sesquioxides used in high-temperature and optical applications. This material is primarily of research and specialized industrial interest, valued for its thermal stability, optical transparency in the infrared spectrum, and potential as a host matrix for laser-active dopants or as a refractory component in extreme-environment systems. Engineers select rare-earth oxide ceramics like Yb₃Y when conventional ceramics cannot meet combined requirements for thermal shock resistance, chemical inertness at very high temperatures, or specific optical/photonic properties.
