Ferrite yog hlau oxide ntawm ferrous alloy.Nyob rau hauv cov nqe lus ntawm hluav taws xob, ferrites muaj ib tug ntau dua resistivity tshaj elemental hlau alloy compositions, thiab kuj muaj zog ntawm dielectric.Lub zog sib nqus ntawm ib chav tsev ntim ntawm ferrite yog tsawg Thaum lub siab zaus tau sau, lub zog sib nqus ntawm ib chav tsev ntim ntawm ferrite tsawg.(Bs) kuj yog lub zog qis (tsuas yog 1/3 ~ 1/5 ntawm cov hlau ntshiab), uas txwv ntau yam kev xaiv thiab txwv cov kev xav tau ntau, thiab tuaj yeem siv dav hauv cov ntawv thov tam sim no muaj zog hauv ntau qhov chaw.
Ferrite yog sintered los ntawm hlau oxides thiab lwm yam khoom xyaw.Feem ntau, nws tuaj yeem muab faib ua peb hom: mus tas li ferrite, mos ferrite thiab gyromagnetic ferrite.
Cov hlau nplaum tas mus li ferrite tseem hu ua ferrite hlau nplaum, uas yog cov hlau nplaum me me uas peb feem ntau pom.Nws cov ntaub ntawv tseem ceeb yog hlau oxide, barium carbonate lossis strontium carbonate.Tom qab magnetization, lub zog ntawm qhov seem hlau nplaum yog siab heev, thiab cov seem hlau nplaum yuav khaws cia rau lub sijhawm ntev.Feem ntau siv los ua cov khoom siv hlau nplaum ruaj khov.Piv txwv: hais lus hlau nplaum.
Mos ferrite yog npaj thiab sintered los ntawm ferric oxide thiab ib los yog ob peb lwm yam hlau oxides (piv txwv li: nickel oxide, zinc oxide, manganese oxide, magnesium oxide, barium oxide, strontium oxide, thiab lwm yam).Nws yog hu ua mos magnetic vim hais tias thaum lub magnetizing magnetic teb ploj, muaj me me los yog tsis muaj residual magnetic teb.Feem ntau yog siv los ua choke coil, lossis cov tub ntxhais ntawm qhov nruab nrab zaus transformer.Qhov no txawv kiag li ntawm ferrite mus tas li.
Gyromagnetic ferrite yog hais txog cov khoom siv ferrite nrog gyromagnetic zog.Lub gyromagnetism ntawm cov khoom sib nqus yog hais txog qhov tshwm sim uas lub dav hlau ntawm polarization ntawm lub dav hlau-polarized electromagnetic yoj propagates nyob rau hauv ib qho kev taw qhia nyob rau hauv cov khoom nyob rau hauv qhov kev txiav txim ntawm ob qho tib si perpendicular DC magnetic teb thiab electromagnetic yoj magnetic teb.Gyromagnetic ferrite tau siv dav hauv kev sib txuas lus microwave.Raws li hom siv lead ua, gyromagnetic ferrite tuaj yeem muab faib ua spinel type, garnet type thiab magnetoplumbite type (hexagonal type) ferrite.
Cov khoom siv hlau nplaum tau siv dav thiab tuaj yeem siv rau hauv electro-acoustic, telecommunications, hluav taws xob ntsuas, motors, nrog rau cov khoom siv nco, microwave Cheebtsam, thiab lwm yam. Nws tuaj yeem siv los sau cov lus, suab paj nruag, thiab cov duab cov ntaub ntawv tapes, cov khoom siv sib nqus. rau cov khoos phis tawj, thiab daim npav sib nqus rau cov neeg caij npav caij npav thiab kev them nqi tsheb.Cov hauv qab no tsom rau cov khoom siv sib nqus siv rau ntawm daim kab xev sib nqus thiab lub hauv paus ntsiab lus ntawm kev ua.
