· JVASP-22950· Lu3O2F5

Lu3O2F5 is a rare-earth oxyfluoride ceramic combining lutetium oxide with fluoride ions, forming a dense crystalline compound. This material belongs to the family of rare-earth fluorides and oxyfluorides, which are primarily investigated for optical, thermal, and specialized high-performance applications where chemical stability and high density are advantageous. Industrial adoption remains limited and largely confined to research settings, but the oxyfluoride ceramic family shows promise in photonics, thermal barrier coatings, and nuclear/radiochemical environments where conventional oxide ceramics may be inadequate.
