Honsen Magneticsithengisa iimagnethi ezineodymium ezinelayisensi.Umazibuthe we-neodymium (ekwabizwa ngokuba yi-NdFeB NIB okanye i-Neo umazibuthe) olona hlobo lusetyenziswa kakhulu lwemagnethi yomhlaba enqabileyo, yimagnethi esisigxina eyenziwe ngealloyi ye-neodymium, intsimbi kunye ne-boron ukwenza i-Nd2Fe14B ye-tetragonal crystalline structure.Yaphuhliswa ngo-1982 nguGeneral Motors kunye neSumitomo Special Metals, iimagnethi zeneodymium lolona hlobo lunamandla lwemagnethi esisigxina efumanekayo kurhwebo.Bathathe indawo yezinye iintlobo zemagnethi kwizicelo ezininzi kwiimveliso zanamhlanje ezifuna iimagnethi ezomeleleyo ezisisigxina, ezinjengeemotor kwizixhobo ezingenazintambo, iihard disk drives kunye neziqhoboshi zemagnethi.Awuqinisekanga ukuba iNeodymium yeyona nto ilungileyo kwisicelo sakho?cofa apha ukufumana uphawu kunye nothelekiso lwesicelo kuzo zonke izixhobo zemagneti esizinikezelayo.
I-Neodymium engqukuva umazibuthe osisigxina Inkcazo
Isakhiwo sekristale ye-tetragonal Nd2Fe14B ine-anisotropy ephezulu ye-uniaxial ye-uniaxial crystalline anisotropy (HA ~ 7 amandla entsimi ye-teslas-magnetic H kwi-A / m ngokuchasene nomzuzu wemagnethi kwi-A.m2).Oku kunika ikhompawundi amandla okuba nonyanzeliso oluphezulu (oko kukuthi, ukuxhathisa ukuba ukhutshwe yimagnethi).I-compound nayo ine-saturation magnetization ephezulu (Js ~ 1.6 T okanye i-16 kG) kwaye ngokuqhelekileyo i-1.3 teslas. Ngoko ke, njengoko ubuninzi bobuninzi bamandla bulingana ne-js2, esi sigaba samagnetic sinamandla okugcina imali enkulu yamandla kazibuthe (BHmax ~ 512). kJ/m3 okanye 64 MG·Oe) Lo mhlaba uphezulu kakhulu kwiialloyi ze-NdFeB kunemagnethi ye-samarium cobalt (SmCo), eyayiludidi lokuqala lwemagnethi yomhlaba enqabileyo ukuthengiswa.Ukuziqhelanisa, iipropathi zemagneti zemagnethi ye-neodymium zixhomekeke kukwakheka kwealloyi, i-microstructure, kunye nobuchule bokuvelisa obusetyenzisiweyo.n45 neodymium umazibuthe disc
