Lutetiumyog lub ntiaj teb tsis tshua muaj cov khoom siv nrog tus nqi siab, tsawg kawg nkaus, thiab siv tsawg.Nws yog mos thiab soluble nyob rau hauv dilute acids, thiab maj mam react nrog dej.
Cov isotopes tshwm sim muaj xws li 175Lu thiab ib nrab-lub neej ntawm 2.1 × 10 ^ 10 xyoo β Emitter 176Lu.Nws yog tsim los ntawm kev txo Lutetium(III) fluoride LuF ∨ · 2H ₂ O nrog calcium.
Kev siv lub ntsiab yog raws li lub catalyst rau roj av tawg, alkylation, hydrogenation, thiab polymerization tshwm sim;Tsis tas li ntawd, Lutetium tantalate kuj tseem siv tau los ua cov khoom siv X-ray fluorescent hmoov;177Lu, radionuclide, tuaj yeem siv rau kev kho mob qog noj ntshav.
Nrhiav keeb kwm
Tshawb nrhiav los ntawm: G. Urban
Tshawb nrhiav hauv 1907
Lutetium tau muab cais tawm ntawm ytterbium los ntawm Fab Kis tus kws tshuaj Ulban hauv xyoo 1907 thiab tseem yog lub ntiaj teb tsis tshua pom thiab pom tseeb thaum xyoo pua 20th.Lub npe Latin rau lutetium los ntawm lub npe qub ntawm Paris, Fabkis, uas yog qhov chaw yug ntawm Nroog.Kev tshawb pom ntawm lutetium thiab lwm lub ntiaj teb tsis tshua muaj lub ntiaj teb europium ua tiav qhov kev tshawb pom ntawm txhua lub ntiaj teb tsis tshua muaj nyob hauv qhov xwm txheej.Lawv qhov kev tshawb pom tuaj yeem suav tias yog qhib qhov rooj plaub rau qhov kev tshawb pom ntawm lub ntiaj teb tsis tshua muaj thiab ua tiav qib plaub ntawm qhov tsis tshua muaj ntiaj teb nrhiav pom.

Lutetium yog cov hlau dawb dawb, uas yog cov hlau hnyav tshaj plaws ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb;Melting point 1663 ℃, boiling point 3395 ℃, ceev 9.8404.Lutetium kuj ruaj khov nyob rau hauv cov huab cua;Lutetium oxide yog cov xim tsis muaj xim uas yaj hauv cov kua qaub los ua cov ntsev tsis muaj xim sib xws.
Lub ntiaj teb tsis tshua muaj hlau nplaum ntawm lutetium yog nruab nrab ntawm cov nyiaj thiab hlau.Cov ntsiab lus impurity muaj feem cuam tshuam rau lawv cov khoom, yog li feem ntau muaj qhov sib txawv tseem ceeb hauv lawv lub cev hauv cov ntaub ntawv.
Hlau yttrium, gadolinium, thiab lutetium muaj zog corrosion kuj thiab muaj peev xwm tswj tau lawv cov xim hlau rau lub sijhawm ntev.
Daim ntawv thov
Vim muaj teeb meem ntau lawm thiab tus nqi siab, lutetium muaj ob peb kev lag luam siv.Cov khoom ntawm lutetium tsis txawv ntawm lwm cov hlau lanthanide, tab sis nws cov reserves kuj me me, yog li nyob rau hauv ntau qhov chaw, lwm yam lanthanide hlau feem ntau yog siv los hloov lutetium.
Lutetium tuaj yeem siv los ua qee qhov tshwj xeeb alloys, xws li Lutetium aluminium alloy tuaj yeem siv rau Neutron activation tsom xam.Lutetium kuj tseem siv tau los ua ib qho catalyst rau roj av tawg, alkylation, hydrogenation, thiab polymerization tshwm sim.Tsis tas li ntawd, doping lutetium nyob rau hauv qee lub laser muaju xws li Yttrium aluminium garnet tuaj yeem txhim kho nws txoj haujlwm laser thiab kho qhov muag sib xws.Tsis tas li ntawd, lutetium kuj tseem siv tau rau phosphors: Lutetium tantalate yog cov khoom siv dawb tshaj plaws uas paub tam sim no, thiab yog cov khoom siv zoo tshaj plaws rau X-ray phosphors.
177Lu yog ib qho hluavtaws radionuclide, uas tuaj yeem siv rau kev kho mob qog noj ntshav.
