Ferrite magnetic hmoov khoom siv txoj kev ua cov txheej txheem

Ferrite yog cov hlau oxide ntawm ferrous alloy. Hais txog hluav taws xob, ferrites muaj ntau dua ntau dua li lub ntsiab hlau alloy muaj pes tsawg leeg, thiab tseem muaj cov khoom ntawm dielectric. Lub zog nqus hluav taws xob ib feem hauv cov ferrite yog tsawg thaum cov loj heev yog tsim, lub zog sib nqus ntawm cov ferrite yog tsawg. (BS) kuj muaj tsawg-lub zog (tsuas yog 1/3 ~ 1/5 ntawm cov tshuaj ntshiab), uas tau siv dav dav siv hauv cov ntawv thov muaj zog tam sim no nyob rau ntau daim ntaub ntawv.

Ferrite yog sintered los ntawm hlau oxides thiab lwm yam khoom xyaw. Feem ntau, nws tuaj yeem faib ua peb hom: ferrite tas mus li, mos ferrite thiab gyromagnetic ferrite.

Cov hlau nplaum tas mus li tseem yog hu ua Ferrite magnet, uas yog cov hlau nplaum dub me me peb feem ntau pom. Nws lub ntsiab ntawv raw yog hlau oxide, Barium carbonate lossis strontium carbonate. Tom qab magnetization, lub zog ntawm cov chaw sib nqus sib nqus yog cov siab heev, thiab cov teb sib nqus uas tuaj yeem tswj tau ntev. Feem ntau siv raws li cov khoom siv hlau nplaum tas mus li. Piv txwv li: Hais lus hlau nplaum.

Mos ferrite tau npaj thiab sintereded los ntawm ferric oxide (piv txwv li cov neeg hlau oxide ( Nws yog hu ua mos sib nqus tau vim thaum magnetizing sib nqus daim teb ploj lawm, muaj me me lossis tsis muaj kev sib nqus sib nqus. Feem ntau siv los ua choke cheese, lossis cov tseem ceeb ntawm cov hluav taws xob theem nrab hloov. Qhov no yog txawv kiag li ntawm cov ferrite tas mus li.

Gyromagnetic ferrite yog hais txog cov khoom siv ferrite nrog Gyromagnetic cov khoom. Lub Gyromagnetism ntawm cov khoom sib nqus yog hais txog qhov tshwm sim uas lub dav hlau ntawm lub dav hlau-polarized hluav taws xob teb thiab hluav taws xob yoj sib nraus teb. Gyromagnetic ferrite tau tau siv dav hauv kev sib txuas lus microwave sib txuas lus. Raws li hom crystal, Gyromagnetic ferrite tuaj yeem faib ua spinning hom, garnet hom spypet thiab magningoplumbite hom (hexagonal hom (hexagonal hom) ferrite.

Cov ntaub ntawv sib nqus tau siv dav thiab tuaj yeem siv rau hauv Electro-Acoustic, thiab lwm yam khoom siv rau cov neeg caij npav thiab cov khoom lag luam tus nqi npav. Hauv qab no tsom rau cov ntaub ntawv sib nqus uas siv rau ntawm cov kab nyias nyias thiab cov ntsiab cai ntawm kev nqis tes ua.
