I-Magic Rare Earth Element: Lutetium

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 kanye 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.

I-Lutetium Metal

I-lutetium iyinsimbi emhlophe eyisiliva, eyinsimbi eqinile neminyene kakhulu phakathi kwezakhi zomhlaba ezingavamile; Iphoyinti 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 kakhulu, 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 njengamanje, futhi iyimpahla efanelekile yama-X-ray phosphors.

I-177Lu iyi-radionuclide yokwenziwa, engasetshenziselwa ukwelapha izimila ngama-radiotherapy.
