Mwachidule

Permanent ferrite maginito, wotchedwanso mwakhama maginito, ndi sanali zitsulo maginito chuma.Mu 1930, Kato ndi Wujing anapeza mtundu wa spinel (MgA12O4) maginito okhazikika, amene ndi prototype wa ferrite chimagwiritsidwa ntchito masiku ano.Ferrite maginito makamaka anapanga. wa SrO kapena Bao ndi Fe2O3 monga zopangira ndi ceramic ndondomeko (pre kuwombera, kuphwanya, pulverizing, kukanikiza, sintering ndi akupera).Ili ndi mawonekedwe a loop yotalikirapo ya hysteresis, mphamvu yokakamiza komanso kukhazikika kwakukulu.Ndi mtundu wazinthu zogwirira ntchito zomwe zimatha kusunga maginito osasinthika kamodzi kokha.Kachulukidwe ake ndi 4.8g/cm3.Malinga ndi njira zosiyanasiyana zopangira, maginito a ferrite amatha kugawidwa m'mitundu iwiri: sintering ndi bonding.Sintering akhoza kugawidwa mu kukanikiza youma ndi chonyowa kukanikiza, ndi kugwirizana akhoza kugawidwa mu extrusion, psinjika ndi jekeseni akamaumba.Maginito ofewa, otanuka komanso opindika opangidwa ndi ufa wa ferrite ndi mphira wopangira amatchedwanso maginito a rabara.Kutengera ngati mphamvu ya maginito yakunja ikugwiritsidwa ntchito kapena ayi, imatha kugawidwa kukhala maginito okhazikika a isotropic ndi maginito okhazikika a anisotropic.

Yerekezerani ndi maginito ena

Ubwino:Mtengo wotsika, gwero lalikulu la zopangira, kukana kutentha kwambiri (mpaka 250 ℃) ndi kukana dzimbiri.

kuipa: Poyerekeza ndi mankhwala NdFeB, remanence ake ndi otsika kwambiri.Kuphatikiza apo, chifukwa cha mawonekedwe otayirira komanso osalimba azinthu zake zotsika kachulukidwe, njira zambiri zogwirira ntchito ndizochepa nazo, monga kukhomerera, kukumba, ndi zina zambiri, mawonekedwe ake ambiri amatha kukanidwa ndi nkhungu, mankhwalawo. kulolerana bwino ndi osauka, ndipo nkhungu mtengo ndi mkulu.

Zokutira:Chifukwa cha kukana kwake bwino kwa dzimbiri, sichifunikira chitetezo chotchingira.
