I-Lutetiuminto yomhlaba eyivelakancane eyivelakancane enamanani aphezulu, izinqolobane ezincane, nokusetshenziswa okulinganiselwe.Ithambile futhi iyancibilika kuma-asidi acwebileyo, futhi ingasabela kancane kancane emanzini.
Ama-isotopes enzeke ngokwemvelo ahlanganisa i-175Lu kanye nengxenye yempilo engu-2.1 × 10 ^ iminyaka engu-10 ubudala β Emitter 176Lu.Yenziwa ngokunciphisa i-Lutetium(III) fluoride LuF ∨ · 2H ₂ O nge-calcium.
Ukusetshenziswa okuyinhloko kunjenge-catalyst ye-petroleum cracking, alkylation, hydrogenation, kanye ne-polymerization reactions;Ngaphezu kwalokho, i-Lutetium tantalate ingasetshenziswa futhi njenge-X-ray fluorescent powder;I-177Lu, i-radionuclide, ingasetshenziselwa i-radiotherapy yamathumba.
Ukuthola Umlando
Kutholwe ngu: G. Urban
Kutholwe ngo-1907
I-Lutetium yahlukaniswa ne-ytterbium ngusokhemisi ongumFulentshi u-Ulban ngo-1907 futhi yayiyinto yomhlaba eyivelakancane eyatholwa futhi yaqinisekiswa ekuqaleni kwekhulu lama-20.Igama lesiLatini le-lutetium livela egameni lasendulo laseParis, eFrance, okuyindawo yokuzalwa yase-Urban.Ukutholakala kwe-lutetium nenye ingxenye yomhlaba engavamile i-europium kuqedele ukutholakala kwazo zonke izakhi zomhlaba ezingavamile ezikhona emvelweni.Ukutholwa kwabo kungabhekwa njengokuvula isango lesine lokutholwa kwezinto ezingavamile zomhlaba kanye nokuqedela isigaba sesine sokutholwa kwezinto ezingavamile zomhlaba.
Ukucushwa kwe-electron
Amalungiselelo e-elekthronikhi:
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d1
I-lutetium iyinsimbi emhlophe eyisiliva, eyinsimbi eqinile neminyene kakhulu phakathi kwezakhi zomhlaba ezingavamile;Iphuzu elincibilikayo 1663 ℃, iphoyinti abilayo 3395 ℃, ukuminyana 9.8404.I-lutetium izinzile emoyeni;I-Lutetium oxide iyikristalu engenambala encibilika kuma-asidi ukuze yakhe usawoti ongenambala ohambisanayo.
I-lutetium metallic luster yomhlaba engavamile iphakathi kwesiliva nensimbi.Okuqukethwe ukungcola kunomthelela omkhulu ezimpahleni zabo, ngakho-ke kuvame ukuba nomehluko obalulekile ezicini zabo ezibonakalayo ezincwadini.
I-Metal yttrium, i-gadolinium, ne-lutetium inokumelana nokugqwala okuqinile futhi ingagcina ukukhanya kwayo kwensimbi isikhathi eside.
Isicelo
Ngenxa yobunzima bokukhiqiza kanye namanani aphezulu, i-lutetium inokusetshenziswa okumbalwa kwezohwebo.Izakhiwo ze-lutetium azihlukile kakhulu kwezinye izinsimbi ze-lanthanide, kodwa izinqolobane zayo zincane, ngakho-ke ezindaweni eziningi, ezinye izinsimbi ze-lanthanide zivame ukusetshenziswa esikhundleni se-lutetium.
I-Lutetium ingasetshenziswa ukwenza ama-alloys akhethekile, njenge-Lutetium aluminium alloy ingasetshenziselwa ukuhlaziywa kokuvula i-Neutron.I-Lutetium ingasetshenziswa futhi njenge-catalyst ye-petroleum cracking, i-alkylation, i-hydrogenation, ne-polymerization reactions.Ngaphezu kwalokho, i-doping lutetium kwamanye amakristalu e-laser njenge-Yttrium aluminium garnet ingathuthukisa ukusebenza kwayo kwe-laser nokufana kokubona.Ukwengeza, i-lutetium ingabuye isetshenziselwe i-phosphors: I-Lutetium tantalate iyimpahla emhlophe ehlangene kunazo zonke eyaziwayo okwamanje, futhi iyimpahla efanelekile yama-X-ray phosphors.
I-177Lu iyi-radionuclide yokwenziwa, engasetshenziselwa ukwelapha izimila ngama-radiotherapy.
