Cov qauv ntawm NdFeB hlau nplaum yog dab tsi?

NdFeB hlau nplaum, yog cov hlau nplaum tsawg hauv ntiaj teb uas tau siv dav hauv ntau yam kev lag luam thiab kev lag luam vim lawv cov khoom sib nqus zoo heev.Cov hlau nplaum no paub txog lawv lub zog siab, ua haujlwm rau demagnetization, thiab tus nqi qis, ua rau lawv muaj kev xaiv nrov rau ntau yam khoom siv hluav taws xob, khoom siv kho mob, thiab tshuab.

Tus qauv ntawmNdFeB hlau nplaumNws yog qhov nyuaj heev, tab sis nws yog qhov nyuaj uas muab lawv cov khoom tshwj xeeb.Cov hlau nplaum no yog tsim los ntawm kev sib xyaw ntawm neodymium, hlau, thiab boron, nrog rau me me ntawm lwm cov ntsiab lus ntxiv los txhim kho lawv cov khoom sib nqus.Tus yuam sij rau nws qhov tshwj xeeb sib nqus teb lub zog yog nyob rau hauv kev npaj ntawm atoms nyob rau hauv cov khoom siv lead ua qauv.

Crystal qauv ntawmNdFeB hlau nplaumyog tetragonal lattice nyob rau hauv uas neodymium thiab boron atoms tsim cov khaubncaws sab nraud povtseg nyob rau hauv lub lattice qauv thiab hlau atoms nyob rau hauv qhov chaw ntawm cov khaubncaws sab nraud povtseg.Qhov kev npaj tshwj xeeb ntawm atoms aligns lub atoms 'magnetic moments, tsim kom muaj zog magnetic teb.

Ntxiv rau lawv cov qauv siv lead ua tshwj xeeb,NdFeB hlau nplaumfeem ntau tsim nyob rau hauv ntau yam duab thiab ntau thiab tsawg, nrog rau cov nplooj ntawv, disks, thiab blocks, kom haum rau ntau yam kev siv.Tshwj xeeb,Segment Ndfeb hlau nplaumyog dav siv nyob rau hauv zus tau tej cov motors, generators, sib nqus separators thiab magnetic resonance imaging (MRI) tshuab vim lawv siab sib nqus zog thiab stability.

Hauv cov ntsiab lus, cov qauv ntawm NdFeB hlau nplaum yog qhov tseem ceeb hauv lawv cov khoom sib nqus zoo heev.Lub tetragonal lattice, ua ke nrog cov txheej txheem meej ntawm neodymium, hlau thiab boron atoms, tso cai rau cov hlau nplaum no tuaj yeem ua kom muaj zog sib nqus thiab tiv thaiv demagnetization. Segment Ndfeb hlau nplaum, tshwj xeeb tshaj yog, yog ib qho tseem ceeb hauv ntau hom kev lag luam thiab kev lag luam uas yuav tsum tau muaj zog thiab ruaj khov magnetic teb.
