Ferrite / Ceramic
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 lonse la zopangira, kutentha kukana (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 kukanikizidwa ndi nkhungu, mankhwalawo. kulolerana molondola ndi osauka, ndipo nkhungu mtengo ndi mkulu.
Kupaka: Chifukwa cha kukana kwake bwino kwa dzimbiri, sifunika kutetezedwa kwa zokutira.
Samarium cobalt
Samarium cobalt maginito ndi mtundu wa maginito osowa padziko lapansi.Ndi mtundu wa zida za maginito zopangidwa ndi samarium, cobalt ndi zitsulo zina zosowa zapadziko lapansi kudzera mugawo, kusungunuka kukhala aloyi, kuphwanya, kukanikiza ndi sintering.Ili ndi mphamvu ya maginito yamphamvu kwambiri komanso kutentha kochepa kwambiri.The pazipita ntchito kutentha akhoza kufika 350 ℃, ndi kutentha zoipa alibe malire.Pamene kutentha ntchito pamwamba 180 ℃, pazipita maginito mphamvu mankhwala (BHmax) ndi coercivity (co Kukhazikika kutentha ndi kukhazikika kwa mankhwala ndi apamwamba kuposa a NdFeB.
Alnico
Al Ni Co ndi aloyi wopangidwa ndi aluminiyamu, faifi tambala, cobalt, chitsulo ndi zinthu zina zachitsulo.Ili ndi remanence yayikulu, kukakamiza kochepa, kukana bwino kwa dzimbiri, kutsika kwa kutentha, kukana kutentha kwambiri, kukana chinyezi, kukana kwamphamvu kwa dzimbiri, kosavuta kuyimitsa oxidize komanso kukhazikika kogwira ntchito.Sintered al Ni Co imapangidwa ndi zitsulo za ufa.Amagwiritsidwa ntchito kwambiri pazigawo zamagalimoto, zida, mota, ma electroacoustic, kulumikizana, magnetoelectric switch, sensa, kuphunzitsa ndi zakuthambo.
Flexible Rubber Magnet
Maginito osinthika amafanana kwambiri ndi maginito opangidwa ndi jakisoni koma amapangidwa m'mizere yosalala ndi ma sheet.Maginitowa ndi otsika mu mphamvu ya maginito ndipo amasinthasintha kwambiri malinga ndi zipangizo zomwe zimagwiritsidwa ntchito pamagulu ndi maginito ufa.Vinyl nthawi zambiri amagwiritsidwa ntchito mumtundu uwu wa maginito ngati binder.
