Kupeza Mbiri
Apezeka ndi: G. Urban
Inapezeka mu 1907
Lutetium inalekanitsidwa ndi ytterbium ndi katswiri wa zamankhwala wa ku France Ulban mu 1907 ndipo inalinso chinthu chosowa padziko lapansi chomwe chinapezedwa ndikutsimikiziridwa kumayambiriro kwa zaka za zana la 20.Dzina lachilatini la lutetium limachokera ku dzina lakale la Paris, France, lomwe ndi malo obadwirako Urban.Kupezeka kwa lutetium ndi chinthu china chosowa padziko lapansi europium kunamaliza kutulukira kwa zinthu zonse zapadziko lapansi zomwe zimapezeka m'chilengedwe.Kupeza kwawo kungaganizidwe ngati kutsegulira chipata chachinayi chakupezeka kwa zinthu zapadziko lapansi zosowa ndikumaliza gawo lachinayi la kutulukira zinthu zapadziko lapansi.

Lutetium ndi chitsulo choyera cha siliva, chomwe ndi chitsulo cholimba kwambiri komanso cholimba kwambiri pakati pa zinthu zosowa zapadziko lapansi;Malo osungunuka 1663 ℃, malo otentha 3395 ℃, osalimba 9.8404.Lutetium imakhala yokhazikika mumlengalenga;Lutetium oxide ndi kristalo wopanda mtundu womwe umasungunuka mu zidulo kupanga mchere wopanda mtundu.
Kuwala kwachitsulo kosowa padziko lapansi kwa lutetium kuli pakati pa siliva ndi chitsulo.Zomwe zili zonyansa zimakhudza kwambiri katundu wawo, choncho nthawi zambiri pamakhala kusiyana kwakukulu kwa thupi lawo m'mabuku.
Metal yttrium, gadolinium, ndi lutetium ali ndi kukana kwamphamvu kwa dzimbiri ndipo amatha kukhalabe ndi chitsulo chonyezimira kwa nthawi yayitali.
Kugwiritsa ntchito
Chifukwa cha zovuta kupanga komanso kukwera mtengo, lutetium ilibe ntchito zochepa zamalonda.Makhalidwe a lutetium sali osiyana kwambiri ndi zitsulo zina za lanthanide, koma nkhokwe zake ndizochepa, choncho m'malo ambiri, zitsulo zina za lanthanide zimagwiritsidwa ntchito m'malo mwa lutetium.
Lutetium angagwiritsidwe ntchito popanga ma aloyi apadera, monga Lutetium aluminiyamu aloyi angagwiritsidwe ntchito posanthula Neutron activation.Lutetium itha kugwiritsidwanso ntchito ngati chothandizira kuphwanya mafuta, alkylation, hydrogenation, ndi polymerization reaction.Kuphatikiza apo, doping lutetium mu makhiristo ena a laser monga Yttrium aluminium garnet amatha kusintha magwiridwe ake a laser komanso mawonekedwe ake.Kuphatikiza apo, lutetium itha kugwiritsidwanso ntchito ngati phosphor: Lutetium tantalate ndizinthu zoyera zophatikizika kwambiri zomwe zimadziwika pakali pano, ndipo ndizinthu zabwino kwambiri za X-ray phosphors.
177Lu ndi radionuclide kupanga, amene angagwiritsidwe ntchito radiotherapy zotupa.
