Muaj xya isotopes ntawm neodymium nyob rau hauv qhov xwm: neodymium 142, 144, 146, ntawm neodymium 142 muaj cov ntsiab lus siab tshaj plaws. Nrog rau lub hnub yug ntawm preasodymium, neodymium tuaj rau hauv ua. Lub sijhawm tuaj txog ntawm cov neeg neodymium qhib lub ntiaj teb tsis tshua muaj kev lag luam thiab ua lub luag haujlwm tseem ceeb hauv IT.YWM kev ua haujlwm hauv ntiaj teb tsis tshua muaj.

Nrhiav pom ntawm neodymium

Karl Orvon Welsbach (1858-1929), tus nrhiav khoom ntawm neodymium

Xyoo 1885, Austrian Chemist Carl Orvon Welsbach Carl Auer Von Welsbach nrhiav neeg neodymium hauv Vienna. Nws cais tawm neodymium thiab preodymium los ntawm kev cais tawm thiab crystallizing ammonydate los ntawm nitricat illated ntawm cov ntawv ntshiab kom txog xyoo 1925.

Txij li thaum xyoo 1950, siab purity neodymium (tshaj 99%) feem ntau tau txais los ntawm ion sib pauv cov txheej txheem ntawm monazite. Cov hlau nws tus kheej yog tau txais los ntawm cov electrolyzing nws cov ntsev ntau. Tam sim no, feem ntau neodymium tau muab rho tawm los ntawm (CE, LA, ND, PR) CO3F hauv Benglea Nathanite thiab lim los ntawm cov kuab tshuaj ntxiv. Ion Txauv Purification Reservification uas ntau tshaj plaws purity (feem ntau> 99.99% rau kev npaj.Tag tau nyob ntawm cov khoom lag luam, thiab ib lub suab liab ntau dua lossis cov xim txiv kab ntxwv dua li cov tshiab version.

Neodymium hlau

Nws yog xim hlau neodymium muaj cov nyiaj ci ci ntsa iab me me ntawm 1024 ° C, ntom ntawm 7.004 g / cm, thiab paramagnetism. Neodymium yog ib qho ntawm feem ntau nquag muaj cov hlau tsis tshua muaj zog, oxidly oxidly txheej thiab tom qab ntawd Peels tawm, nthuav tawm cov hlau mus ntxiv oxidation. Yog li ntawd, neodymium qauv nrog qhov loj me ntawm ib centimeter yog ua kom tag oxidized tsis pub dhau ib xyoos. Nws nthuav tawm maj mam nyob rau hauv dej txias thiab sai sai hauv dej kub.

Neodymium electronic configuration

Kev teeb tsa hluav taws xob:

1s2 2S2 2P6 3S2 3P6 4S2 3D10 4S2 4D10 5P6 6S2 4F4

Lub laser kev ua tau zoo ntawm neodymium yog tshwm sim los ntawm kev hloov pauv ntawm 4F orbital electrons ntawm cov zog sib txawv. Cov khoom siv laser no tau siv nyob rau hauv kev sib txuas lus, cov ntaub ntawv cia, kev kho mob, tshuab xoos, thiab cov khoom siv NOD efficiency.

Daim ntawv thov ntawm neodymium

Cov neeg siv ntau tshaj plaws ntawm neodymium yog ndfeb cov khoom lag luam tas mus li. NdFeB hlau nplaum yog hu ua "tus huab tais ntawm cov hlau nplaum tas mus li" vim hais tias ntawm nws lub zog sib nqus khoom. Nws yog dav siv nyob rau hauv electronics, tshuab thiab lwm yam lag luam rau nws ua tau zoo heev. Francis phab ntsa, tus xibfwb ntawm kev thov siv tau nrog cov hlau nplaum Almina .Qhov no muaj peev xwm sib tw nrog cov khoom sib nqus ntawm Alpha sib tw Spectrometer qhia tias cov khoom sib nqus ntawm NDFEX hlau nplaum nyob rau hauv Tuam Tshoj tau nkag mus hauv thoob ntiaj teb kawm.

Neodymium hlau nplaum ntawm Hard Disk

Neodymium tuaj yeem siv los ua ceramics, ci lub khob paj yeeb, dag ruby ​​hauv laser thiab tshwj xeeb iav uas tuaj yeem lim infrared rays. Siv ua ke nrog praseodymium ua rau gggles rau iav beanders.

Ntxiv 1.5% ~ 2.5% nano neodymium oxide nkag mus rau hauv cov pa hluav taws xob, thiab nws tau siv dav siv raws li cov khoom siv aerospace rau kev ua lag luam.

NANO-YTTRIUM ALUMINNET DOPED NROG NOODYMIUM OXIDE STET, uas yog dav siv rau cov ntaub ntawv LWDE, uas yog siv cov khoom siv thickness hauv qab no 10 hli hauv kev lag luam.

ND: YAG Laser Qws

Hauv kev kho mob, nano yttrium txhuas garnet laser doped nrog nano neodymium oxide oxide siv los kho tus mob phais lossis riam phom.

Neodymium iav yog ua los ntawm kev ntxiv neodymium oxide rau hauv lub khob yaj. Lavender feem ntau tshwm nyob rau hauv neodymium iav nyob rau hauv lub hnub ci lossis teeb lub teeb, tab sis lub teeb xiav tshwm sim lub teeb lub teeb fluorescent. Neodoomium tuaj yeem siv los xim ua xim pleev xim ntawm iav xws li cov violet ntshiab, cawv liab thiab sov grey.

neodymium iav

Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis thiab kev nthuav dav thiab kev txuas ntxiv ntawm lub ntiaj teb kev tshawb fawb tsis tshua muaj zog thiab thev naus laus zis yuav muaj qhov chaw siv hluav taws xob
