Rare ntiaj teb keeb | Neodymium (Nd)

Nrog yug ntawm praseodymium keeb, neodymium keeb kuj tshwm sim. Kev tuaj txog ntawm neodymium caij tau qhib lub ntiaj teb tsis tshua muaj teb, ua lub luag haujlwm tseem ceeb hauv thaj av tsis tshua muaj, thiab tswj hwm lub ntiaj teb tsis tshua muaj kev lag luam.

Neodymium tau dhau los ua lub ntsiab lus kub hauv kev ua lag luam rau ntau xyoo vim nws txoj haujlwm tshwj xeeb hauv thaj chaw tsis tshua muaj ntiaj teb. Cov neeg siv loj tshaj plaws ntawm cov hlau neodymium yog neodymium hlau boron cov khoom siv hlau nplaum ruaj khov. Qhov tshwm sim ntawm neodymium hlau boron mus tas li hlau nplaum tau txhaj tshuaj tshiab thiab tseem ceeb rau hauv thaj tsam ntawm lub ntiaj teb tsis tshua muaj high-tech. Neodymium hlau boron hlau nplaum muaj cov khoom siv hluav taws xob zoo sib nqus thiab paub tias yog "tus huab tais ntawm cov hlau nplaum ruaj khov". Lawv tau siv dav hauv kev lag luam xws li electronics thiab machinery vim lawv cov kev ua tau zoo heev. Txoj kev vam meej ntawm Alpha Magnetic Spectrometer cim tau tias ntau yam khoom sib nqus ntawm Nd-Fe-B hlau nplaum hauv Suav teb tau nkag mus rau qib ntiaj teb.

Neodymium kuj tseem siv rau hauv cov khoom siv hlau tsis muaj hlau. Ntxiv 1.5% mus rau 2.5% neodymium rau magnesium lossis aluminium alloys tuaj yeem txhim kho lawv cov kev ua haujlwm kub, airtightness, thiab corrosion kuj, ua rau lawv siv dav hauv aerospace cov ntaub ntawv. Tsis tas li ntawd, neodymium doped yttrium aluminium garnet generates luv yoj laser beams, uas yog dav siv nyob rau hauv kev lag luam rau vuam thiab txiav nyias cov ntaub ntawv nrog ib tug tuab ntawm tsawg tshaj li 10 hli. Hauv kev kho mob, neodymium doped yttrium aluminium garnet laser yog siv los ntawm scalpel tshem tawm kev phais lossis tshuaj tua kab mob. Neodymium kuj tseem siv rau cov xim iav thiab cov ntaub ntawv ceramic thiab ua ib qho ntxiv hauv cov khoom siv roj hmab. Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, nrog rau kev nthuav dav thiab txuas ntxiv ntawm thaj chaw ntawm lub ntiaj teb tsis tshua muaj thev naus laus zis, neodymium yuav muaj ntau qhov chaw siv.
