Ferrite / Ceramic
Dulmar:
1930-kii, Kato iyo Wujing waxay heleen nooc ka mid ah spinel (MgA12O4) magnet joogto ah, kaas oo ah nooca ferrite si ballaaran loo isticmaalo maanta. Ferrite magnet ayaa inta badan la sameeyaa. ee SrO ama Bao iyo Fe2O3 sida alaabta ceeriin ee habka dhoobada (ka hor ridida, burburinta, miirida, riixida, sintayn iyo shiidi). Waxay leedahay sifooyinka loop loop ballaaran, xoog xoog badan iyo sii joogitaan sare. Waa nooc ka mid ah maaddooyinka shaqaynaya oo xajin kara magnetism-ka joogtada ah mar magnetized. Cufnaantiisu waa 4.8g/cm3. Marka loo eego hababka wax soo saarka ee kala duwan, magnet ferrite waxaa loo qaybin karaa laba nooc: sintering iyo bonding. Sintering waxaa loo qaybin karaa cadaadis qalalan iyo cadaadis qoyan, iyo bonding waxaa loo qaybin karaa extrusion, cadaadis iyo qaabaynta irbado. Magnet-ka jilicsan, laastiga ah iyo qalloocan ee ka samaysan budada ferrite ee isku xidhan iyo caagga synthetic ayaa sidoo kale loo yaqaan magnet-ka caagga ah. Sida laga soo xigtay haddii garoonka magnetic dibadda la codsado iyo in kale, waxa loo qaybin karaa isotropic magnet joogto ah iyo magnet joogto ah anisotropic.
Is barbar dhig qalabka birlabeedka kale
Faa'iidada: Qiimaha hoose, ilaha ballaaran ee alaabta ceeriin, caabbinta heerkulka sare (ilaa 250 ℃) iyo iska caabinta daxalka.
Khasaaro: Marka la barbar dhigo alaabada NdFeB, joogitaankeedu aad buu u hooseeyaa. Intaa waxaa dheer, iyadoo ay sabab u tahay qaab-dhismeedka yara dabacsan oo jilicsan ee walxaha cufnaanta hoose, habab badan oo wax-qabad ah ayaa xaddidan, sida feerka, qodista, iwm., inta badan qaabka sheyga ayaa kaliya lagu cadaadin karaa caaryada, alaabta. saxnaanta dulqaadku waa liidata, qiimaha caaryadana waa sarreeyaa.
Dahaarka: Sababtoo ah caabbinta daxalka aadka u fiican, uma baahna ilaalinta daahan.
Samarium cobalt
Samarium cobalt magnet waa nooc ka mid ah birlab dhulka dhif ah. Waa nooc ka mid ah qalabka birlabeedka oo ka samaysan samarium, cobalt iyo walxo kale oo bir ah oo naadir ah iyadoo loo eegayo saamiga, ku dhalaali kara daawaha, burburinta, riixida iyo isku dhafka. Waxay leedahay wax soo saarka tamarta birlabeedka sare iyo heerkulka aad u hooseeya. Heerkulka ugu badan ee shaqada wuxuu gaari karaa 350 ℃, heerkulka xununa waa mid aan xadidneyn. Marka heerkulka shaqadu uu ka sarreeyo 180 ℃, badeecadeeda tamarta magnetic ugu badan (BHmax) iyo qasbidda (co Dejinta heerkulka iyo xasiloonida kiimikada ayaa ka sarreeya kuwa NdFeB
Alnico
Al Ni Co waa daawaha ka kooban aluminium, nikkel, cobalt, birta iyo walxo kale oo bir raad. Waxay leedahay remanence sare, jujuub hooseeyo, caabbinta daxalka wanaagsan, heerkulka hooseeyo, iska caabin heerkulka sare, caabbinta huurka, iska caabin daxalka xooggan, ma fududa in oxidize iyo xasilloonida shaqada wanaagsan. Sintered al Ni Co waxaa soo saara macdanta budada ah. Waxaa si weyn loo isticmaalaa in qaybaha baabuurta, instrumentation, motor, electroacoustic, isgaarsiinta, magnetoelectric biiro, dareenka, waxbaridda iyo aerospace.
Magnet caag dabacsan
Magnet-yaasha dabacsani waxay aad ugu shabahaan birlabyada qaabaysan ee la isku duro laakiin waxaa lagu soo saaraa xariijimo fidsan iyo go'yaal. Magnet-yadani way ka hooseeyaan xoogga birlabeedka aadna way u dabacsan yihiin iyadoo ku xidhan agabka loo isticmaalay xarunta budada magnetic. Vinyl waxaa inta badan loo isticmaalaa nooca magnetka ah sida binder.
