Qhov sib txawv tseem ceeb ntawm cov hlau nplaum neodymium thiab cov hlau nplaum ceramic yog cov hlau nplaum neodymium yog cov hlau nplaum hlau, hos cov hlau nplaum ceramic yog cov hlau nplaum uas tsis yog xim hlau.
Ib lub hlau nplaum tuaj yeem txhais tau tias yog ib daim hlau lossis lwm yam khoom siv uas muaj nws cov khoom siv atoms nyob rau hauv qhov kev txiav txim qhov teeb meem uas cov khoom qhia cov khoom ntawm hlau nplaum, nrog rau kev nyiam ntawm lwm yam khoom uas muaj hlau. Cov hlau nplaum neodymium yog hom hlau nplaum uas tsis tshua muaj hauv ntiaj teb, thaum cov hlau nplaum ceramic yog cov nqi qis rau cov hlau nplaum hlau.
Neodymium Magnet yog dab tsi?
Neodymium hlau nplaum yog hom hlau nplaum uas tsis tshua muaj ntiaj teb siv. Peb tuaj yeem txhais tau tias nws yog cov hlau nplaum ruaj khov uas yog tsim los ntawm cov hlau nplaum ntawm neodymium, hlau thiab boron, tsim cov compound Nd2Fe14B nrog cov qauv tetragonal crystalline.
Cov hlau nplaum no yog cov hlau nplaum uas muaj zog tshaj plaws uas muaj nyob rau ntawm kev lag luam. Muaj cov txheej txheem tsim khoom sib txawv rau cov hlau nplaum no, uas ua rau muab faib ua ob pawg li sintered neodymium hlau nplaum thiab sib txuas neodymium hlau nplaum. Ob hom hlau nplaum no muaj ntau daim ntawv thov hauv kev lag luam niaj hnub no, suav nrog cov tshuab hluav taws xob hauv cov cuab yeej cordless, hard disk drives, thiab sib nqus fasteners.
Neodymium hlau nyiam xaj rau hauv daim ntawv sib nqus tsuas yog thaum qhov kub thiab txias, qhov twg cov hlau no zoo li tsim cov kev txiav txim siab antiferromagnetic. Muaj qee cov hlau nplaum ntawm neodymium nrog cov hlau hloov pauv uas tuaj yeem xaj ferromagnetically nrog curie kub uas yog siab dua chav tsev kub. Yog li ntawd, cov hlau no feem ntau yog siv los ua cov hlau nplaum.
Ceramic Magnet yog dab tsi?
Ceramic hlau nplaum yog cov nqi qis dua rau cov hlau nplaum hlau. Cov hlau nplaum no tau tsim nyob rau xyoo 1960 thiab tseem hu ua ferrite hlau nplaum. Cov ntaub ntawv no muaj hlau oxide thiab strontium carbonate. Txawm li cas los xij, cov hlau nplaum no nyuaj, nkig, thiab muaj qhov sib piv qis zog. Cov khoom no nyiam cais cov hlau nplaum no los ntawm qee qhov kev siv. Tab sis cov no tseem ceeb heev nyob rau hauv ib co lwm yam kev siv vim corrosion kuj, demagnetization kuj, thiab tus nqi qis. Cov hlau nplaum no yog thawj qhov kev xaiv rau feem ntau DC motors, sib nqus sib nqus, sib nqus resonance imaging thiab automotive sensors.
Cov cuab yeej siv rau kev npaj cov hlau nplaum ceramic yog hmoov tshuab. Lub ntsiab raw khoom rau kev npaj no yog hlau oxide thiab strontium carbonate. Feem ntau, ob lub tebchaw no sib xyaw ua ke ntawm qhov kub thiab txias qhov twg muaj cov tshuaj tiv thaiv tsim ferrite.
Qhov txawv ntawm Neodymium thiab Ceramic Magnets yog dab tsi?
Neodymium thiab cov hlau nplaum ceramic yog cov khoom siv sib nqus. Qhov sib txawv tseem ceeb ntawm neodymium thiab cov hlau nplaum ceramic yog cov hlau nplaum neodymium yog cov hlau nplaum hlau, hos cov hlau nplaum ceramic yog cov hlau nplaum uas tsis yog hlau. Feem ntau, cov hlau nplaum neodymium yog ua los ntawm cov hlau nplaum ntawm cov hlau neodymium, thaum cov hlau nplaum ceramic yog ua los ntawm cov hlau oxide thiab strontium carbonate tebchaw. Ntxiv mus, tus nqi ntawm kev tsim cov hlau nplaum neodymium yog siab heev, yog li cov hlau nplaum no kim heev. Ntawm qhov tod tes, tus nqi tsim khoom rau cov hlau nplaum ceramic yog tsawg; Yog li, cov hlau nplaum no sib piv tsis tshua kim.
Cov hauv qab no infographic teev qhov sib txawv ntawm neodymium thiab cov hlau nplaum ceramic hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary - Neodymium vs Ceramic Magnets
Neodymium hlau nplaum yog hom hlau nplaum uas tsis tshua muaj ntiaj teb siv. Cov hlau nplaum ceramic yog cov nqi qis dua rau cov hlau nplaum hlau. Qhov sib txawv tseem ceeb ntawm cov hlau nplaum neodymium thiab cov hlau nplaum ceramic yog cov hlau nplaum neodymium yog cov hlau nplaum hlau, hos cov hlau nplaum ceramic yog cov hlau nplaum uas tsis yog xim hlau.
