Litetiumyog qhov tsawg tsawg ntawm cov av tsis tshua muaj txiaj ntsig nrog cov nqi siab, cov peev txheej tsawg, thiab siv tsawg. Nws yog mos thiab soluble hauv dilute acids, thiab tuaj yeem maj mam hnov mob nrog dej.
Lub cev muaj tshwm sim xws li 175LU thiab ib nrab-lub neej ntawm 2.1 × 10 ^ 10 xyoo β emitter 176lu. Nws yog tsim los ntawm kev txo cov lutetium (iii) fluoride lufgenide lufen ∨ 2 ₂ o nrog calcium.
Lub ntsiab siv yog ib qho catalyst forpoleum cracking, alkylation, hydrogenation, thiab polymerization kev tawm tsam; Tsis tas li ntawd, Lutetium TANTALATE kuj tseem siv tau raws li cov khoom siv ntawm x-tshav pob fluorescent hmoov; 177lu, muaj radionuclide, tuaj yeem siv rau kev ntsuas hluav taws xob ntawm cov qog.
Nrhiav keeb kwm
Nrhiav tau los ntawm: G. Nroog
Nrhiav tau xyoo 1907
Lutetium tau sib cais los ntawm Ytterbium los ntawm French Chemist Ulban xyoo 1907 thiab kuj yog lub ntiaj teb tsis tshua muaj kev nrhiav pom thiab paub tseeb nyob rau xyoo pua 20th. Lub npe Latin rau Lutetium los ntawm lub npe qub ntawm Paris thaum ub, Fabkis, uas yog qhov yug ntawm nroog. Qhov pom ntawm Lutetium thiab lwm qhov tsis tshua muaj lub ntiaj teb Ofoptry ua tiav cov kev tshawb pom ntawm txhua lub ntiaj teb tsis tshua muaj nyob hauv xwm. Lawv qhov kev tshawb pom yuav suav tau tias yog qhib lub rooj vag plaub lub rooj vag mus rau qhov nrhiav pom ntawm lub ntiaj teb tsawg thiab ua tiav theem plaub ntawm lub ntiaj teb tsis tshua pom kev.

Lutetium yog ib qho nyiaj dawb hlau, uas yog qhov nyuaj tshaj plaws thiab densest hlau ntawm lub ntiaj teb tsis tshua muaj neeg; Melting point 1663 ℃, boiling point 3395 ℃, ntom 9.8404. Lutetium yog tus muaj nyob hauv huab cua; Lutetium oxide yog qhov tsis muaj xim siv lead ua uas disinolves hauv cov acids los ua cov ntsev tsis muaj xim.
Lub ntiaj teb tsis tshua muaj xim hlau ntawm Lutetium yog ntawm cov nyiaj thiab hlau. Lub tshuab los txawv tebchaws muaj qhov cuam tshuam tseem ceeb ntawm lawv cov yam ntxwv, yog li muaj feem ntau sib txawv hauv lawv cov khoom siv lub cev hauv cov ntaub ntawv.
Hlau yttrium, gadolinium, thiab lub lutetium muaj cov muaj zog corrosion tsis kam thiab tuaj yeem tswj lawv cov xim hlau thiab tawv ncauj
Daim ntawv thov
Vim yog cov nyom ntau yam thiab cov nqi siab, Lutetium muaj ob peb kev ua lag luam siv. Cov yam ntxwv ntawm Lutetium tsis txawv ntawm lwm cov hlau, tab sis nws cov peev txheej tsawg dua, yog li ntau qhov chaw, lwm yam kev sib tw ntawm cov hlau feem ntau yog siv los hloov cov lutetium.
Lutetium tuaj yeem siv los ua qee yam tshwj xeeb, xws li Lutetium aluminoy alloy tuaj yeem siv rau Neuron ua kom tsom xam. Lutetium kuj tseem tuaj yeem siv ua catalyst rau roj av tawg, alkylation, hydrogenation, thiab polymerization kev tawm tsam. Tsis tas li ntawd, doping liutetium hauv qee cov muaj lead av laser xws li yttrium alarnet tuaj yeem txhim kho nws txoj kev ua lag luam laser thiab cov khaub ncaws optical. Tsis tas li ntawd, Lutetium tseem siv tau rau phosphors: Lutetium TANTALATE yog cov khoom siv dawb tshaj plaws paub txog tam sim no, thiab yog cov khoom siv zoo rau xoo hluav taws xob phosphors.
177LU yog cov khoom siv hluav taws xob radionuclide, uas tuaj yeem siv rau kev ntsuas hluav taws xob ntawm cov qog.
