I-Lutetium oxide isetyenziselwa ukuqhwanyaza kweekristale, iiseramikhi, umgubo we-LED, isinyithi, njl.
Yimathiriyeli ekrwada ebalulekileyo yeekristale zelaser, kwaye ikwanosetyenziso olukhethekileyo kwiiseramics, iglasi, iphosphors, iilaser.
I-Lutetium Oxide ikwasetyenziswa njengezinto ezibangela ukuqhekeka, i-alkylation, i-hydrogenation, kunye ne-polymerization.
