Sintered NdFeB yog cov khoom siv sib nqus ua haujlwm siab muaj xws li neodymium, hlau, boron thiab lwm yam kab kawm. Ntawm lawv, NdFeB yog cov khoom siv tseem ceeb thiab ua lub luag haujlwm tseem ceeb.
Ua ntej ntawm tag nrho cov, NdFeB yog lub ntsiab hlau nplaum nyob rau hauv sintered NdFeB cov ntaub ntawv. Ntawm cov khoom sib nqus, hlau yog cov hlau nplaum uas muaj zog tshaj plaws, thaum neodymium kuj muaj lub zog sib nqus thiab zoo heev thaum tshav kub kub. Boron ua lub luag haujlwm hauv kev ruaj khov ntawm cov qauv siv lead ua thiab txhim kho cov hlau nplaum ntawm cov hlau. Kev sib xyaw ntawm peb lub ntsiab lus no ua rau sintered NdFeB cov ntaub ntawv muaj ntau yam zoo heev xws li cov khoom siv hluav taws xob sib nqus, siab coercive thiab siab sib nqus saturation.
Qhov thib ob, qhov zoo thiab purity ntawm NdFeB kuj tseem muaj feem cuam tshuam rau kev ua haujlwm ntawm sintered NdFeB cov ntaub ntawv. Cov khoom zoo thiab siab purity NdFeB tuaj yeem ua kom ntseeg tau cov ntsiab lus sib nqus ntawm cov khoom sib nqus, tswj kev ruaj ntseg ntawm cov qauv siv lead ua, txhim kho cov tawv tawv thiab cov khoom sib nqus ntawm cov khoom, zam kev cuam tshuam ntawm impurities thiab tsis xws luag ntawm kev ua haujlwm ntawm cov khoom, thiab txhim kho corrosion kuj thiab kub tsis kam ntawm cov khoom. Yog li, qhov purity thiab zoo ntawm NdFeB yog tus yuam sij rau kev npaj cov khoom zoo sintered NdFeB.
Hauv luv luv, NdFeB, cov khoom siv tseem ceeb hauv sintered NdFeB cov ntaub ntawv, yog lub hauv paus tseem ceeb ntawm cov khoom siv. Cov khoom sib nqus zoo, ua kom sov zoo thiab cov qauv siv lead ua ruaj khov ntawm NdFeB, nrog rau kev ua haujlwm siab thiab siab purity, txhua tus muaj qhov tseem ceeb ntawm kev ua haujlwm ntawm sintered NdFeB cov ntaub ntawv. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib ntawm thev naus laus zis thiab kev nthuav dav ntawm daim ntawv thov teb, sintered NdFeB yuav muaj tseeb siv dav hauv ntau thaj chaw.
