Product Description

Ferrite Magnet (tseem hu ua cov hlau nplaum ceramic) yog cov hlau nplaum ruaj khov.
Lawv feem ntau yog Strontium raws li (SrFe2O3), tsim nrog Strontium Carbonate additive kom nce kev ua yeeb yam los ntawm cov khoom siv tsis siv neeg Barium raws li (BaFe2O3).
Lawv lub zog quab yuam zoo los ntawm lub siab siv lead ua anisotropy ntawm strontium hlau oxide. Txawm li cas los xij, cov khoom isotropic kuj tuaj yeem tsim tau qhov uas yuav tsum tau ua kom yooj yim thiab yooj yim ntau tus ncej magnetization.
Nyob rau hauv cov nqe lus ntawm cov yam ntxwv ntawm hluav taws xob, lub resistivity ntawm ferrite yog ntau loj dua li ntawm cov hlau thiab hlau alloy magnetic cov ntaub ntawv, thiab nws kuj muaj ntau dua dielectric zog.
Cov khoom sib nqus ntawm ferrite kuj qhia tau tias muaj permeability siab ntawm cov frequencies.
Ferrite tsis yog conductive thiab muaj siab tiv thaiv corrosion, acids, ntsev, thiab lubricants. Cov duab zoo tshaj plaws yog qhov yooj yim, xws li disc, blocks, cylinders, rings, thiab arcs.
Ferrite hlau nplaum yog feem ntau siv nyob rau hauv ntau daim ntawv thov nyob rau hauv ob peb lub xyoo dhau los, xws li hais lus nrov, motors, thiab generators.
