Qhov nrhiav pom ntawmNeodymium
Karl Von Welsbach (1858-1929), Exitner ofNeodymium
Xyoo 1885, Austrian Chemist Carl Auer Von Welsbach nrhiav tauneodymiumNyob rau hauv Vienna. Nws sib caisneodymiumthiabPreaseymiumLos ntawm symmetricalneodymiumCov ntaub ntawv los ntawm kev sib cais crystalline ammonium dinitrate los ntawm nitric acid, thiab sib cais lawv los ntawm kev tsom xam spectral. Txawm li cas los xij, nws tsis tau mus txog xyoo 1925 uas lawv tau sib cais nyob rau hauv ib tug kuj cov ntawv ntshiab.
Txij li thaum xyoo 1950, siab-purity (tshaj 99%)neodymiumtau tsuas yog tau txais los ntawm ion kev sib pauv cov txheej txheem ntawm monazite. Cov hlau nws tus kheej yog tau txais los ntawm electrolysis ntawm nws cov ntsev halide. Tam sim no, feem ntauneodymiumyog rho tawm los ntawm Bastana Pob Zeb (CE, LA, ND, PR) CO3F thiab ua kom huv los ntawm cov kuab tshuaj ntau. Ion hloov pauv kev ua haujlwm yog tshwj tseg rau kev npaj cov kev coj dawb huv (feem ntau> 99.99%). Vim tias qhov nyuaj hauv kev tshem cov kab kawg ntawmPreaseymiumNyob rau hauv lub caij nyoog ntawm kev tsim khoom siv rau ntawm cov kauj ruam-ntawm-kauj ruam crystallization technology, thaum ntxovneodymiumCov khoom siv iav thaum xyoo 1930 tau muaj lub paj yeeb lossis txiv kab ntxwv hu ua cov niaj hnub.
Neodymium hlauMuaj cov nyiaj ci ci ntsa iab me me ntawm 1024 ° C, thiab ntom ntawm 7.004G / cm ³, nws muaj paramagnetism.Neodymiumyog ib qho ntawm cov nquagLub ntiaj teb tsis tshua muaj hlau, uas tau sai heev oxidly oxidly nyob rau hauv huab cua, sib sau ib txheej oxide uas ces peels tawm, nthuav tawm cov hlau rau ntxiv oxidation. Yog li ntawd, ib tug centimeter meneodymiumQauv yog kiag li oxidized nyob rau hauv ib xyoos. Rov qab ua rau cov dej txias thiab hauv dej kub.

Lub laser kev ua haujlwm ntawmneodymiumYog vim yog kev hloov pauv ntawm 4F orbital electrons ntawm cov zog sib txawv. Cov khoom siv laser no yog dav siv hauv kev sib txuas lus, cov ntaub ntawv cia, kev kho mob, ua haujlwm siv tshuab, thiab lwm thaj chaw. Ntawm lawv,yttrium txhuasGarnet Y3al5o12: ND (YAG: ND) tau siv dav rau nws cov kev ua tau zoo, nrog rau ND dopedgadolinium scandiumguanium garnet nrog kev ua haujlwm siab dua.

Tus neeg siv loj tshaj plaws ntawmneodymiumYog neodymium hlau boron tas mus li hlau nplaum cov khoom. Neodymium Hlau Boron Loj Tshaj Plaws muaj cov khoom sib nqus muaj zog thiab yog lub npe hu ua tus vaj ntxwv "King ntawm cov hlau nplaum ruaj khov". Lawv tau siv dav hauv kev lag luam xws li cov khoom siv hluav taws xob thiab cov tshuab thiab ua haujlwm zoo heev. Francis phab ntsa, tus xibfwb ntawm kev thov siv kev sib sau ntawm Cumburn Tsev Kawm Ntawv ntawm Curch, hais tias: "Hais txog cov hlau nplaum, muaj tiag tsis muaj kev sib tw nrogneodymiumCov. " Txoj kev txhim kho zoo ntawm Alpha sib nqus Spectrometer cov cim uas Tuam Tshoj cov khoom sib nqus ntau ntawm cov hlau nplaum ntau ntau tau nce mus txog cov qib hauv ntiaj teb-chav kawm.
Neodymium hlau nplaum ntawm Hard Disk
NeodymiumYuav siv tau los tsim cov khoom siv paj ntaub, paj ntaub paj ntaub, cov iav dag hauv cov iav tshwj xeeb, thiab cov iav tshwj xeeb uas tuaj yeem lim infrared rays. Siv ua ke nrogPreaseymiumkom gggles rau iav cov neeg ua haujlwm tshuab.
Ntxiv 1.5% rau 2.5% nanoneodymium oxideTxhawm rau magnesium lossis aluminium alloys tuaj yeem txhim kho qhov kev ua tau zoo, airtightness, thiab corrosion tsis kam ntawm alloy, thiab yog siv dav ua ib qho khoom siv aerospace.
Nalisyttrium txhuasGarnet doped nrogneodymium oxideTsim cov nthwv dej luv Laser Laser Beams, uas tau siv dav hauv kev lag luam rau vuam thiab txiav cov khoom siv nyias nyias nrog tsawg dua 10 hli.

Hauv kev xyaum kho mob, nanoyttrium txhuasGarnet lasers doped nrog nanoSiab Purity 99.9% Neodymium oxide PE tsis muaj 1313-97-9 (Epomaterial.com)siv hloov ntawm kev phais mob riam los tshem tawm kev phais mob lossis tshuaj tua kab mob.
Neodymiumiav yog tsim los ntawm kev ntxivneodymium oxiderau lub iav yaj. Feem ntau, Lavender tshwm rauneodymiumIav nyob rau hauv lub hnub ci lossis incandescent teeb, tab sis nws pom xiav xiav nyob rau hauv lub teeb pom kev zoo fluorescent.NeodymiumYuav siv tau los xim ua xim muag heev ntawm iav xws li cov neeg ua txhaum cai ntshiab, burgundy, thiab sov grey.
