Ferrite / Keramika
Nānā nui:
ʻO ka magnet ferrite mau loa, i ʻike ʻia ʻo ia hoʻi ʻo ka paʻakikī paʻakikī, he mea non-metallic magnetic material.In 1930, ua ʻike ʻo Kato lāua ʻo Wujing i kahi ʻano spinel (MgA12O4) mau magnet, ʻo ia ka prototype o ka ferrite i hoʻohana nui ʻia i kēia lā. ʻO ka SrO a i ʻole Bao a me Fe2O3 ma ke ʻano he mea maka ma ke kaʻina hana seramika (firing mua, ʻohi, pulverizing, kaomi, sintering a me ka wili).Loaʻa iā ia nā hiʻohiʻona o ka loop hysteresis loop, ka ikaika coercive kiʻekiʻe a me ka remanence kiʻekiʻe.He ʻano mea hana ia e hiki ai ke mālama i ka magnetism i ka manawa i hoʻopaneʻe ʻia.ʻO kona mānoanoa he 4.8g/cm3.Wahi a nā kaʻina hana like ʻole, hiki ke hoʻokaʻawale ʻia ka magnet ferrite i ʻelua ʻano: sintering a me ka hoʻopaʻa ʻana.Hiki ke hoʻokaʻawale ʻia ka Sintering i ke kaomi maloʻo a me ka pulu pulu, a hiki ke hoʻokaʻawale ʻia ka hoʻopaʻa ʻana i extrusion, compression a me ka hoʻoheheʻe ʻana.ʻO ka magnet palupalu, elastic a wili ʻia i hana ʻia me ka pauka ferrite paʻa a me ka ʻōpala synthetic i kapa ʻia ʻo ia ka magnet magnet.E like me ka hoʻohana ʻia ʻana o ke kahua magnetic waho a i ʻole, hiki ke hoʻokaʻawale ʻia i isotropic permanent magnet a me anisotropic permanent magnet.
E hoʻohālikelike me nā mea magnetic ʻē aʻe
Pōmaikaʻi: Ke kumu kūʻai haʻahaʻa, ke kumu ākea o nā mea maka, ke kūpaʻa wela kiʻekiʻe (a hiki i 250 ℃) a me ka pale ʻana i ka corrosion.
Ka pōʻino: Hoʻohālikelike ʻia me nā huahana NdFeB, haʻahaʻa loa kona remanence.Eia kekahi, ma muli o ke ʻano haʻahaʻa a palupalu o kāna mea haʻahaʻa haʻahaʻa, nui nā ʻano hana i kaupalena ʻia e ia, e like me ke kuʻi ʻana, eli, a me nā mea ʻē aʻe, ʻo ka hapa nui o kāna ʻano huahana hiki ke kaomi wale ʻia e ka mold, ka huahana. ʻilihune ka pololei o ka hoʻomanawanui, a he kiʻekiʻe ke kumukūʻai mold.
Ka uhi ʻana: Ma muli o kona kūpaʻa maikaʻi ʻana i ka corrosion, ʻaʻole pono ia i ka pale uhi.
Samarium cobalt
ʻO Samarium cobalt magnet kahi ʻano mea hoʻokalakupua honua.He ʻano mea mea hana magnetic i hana ʻia me ka samarium, cobalt a me nā mea metala ʻē aʻe o ka honua maʻamau ma o ka like ʻana, hoʻoheheʻe ʻia i loko o ka alloy, ʻokiʻoki, kaomi a me ka sintering.Loaʻa iā ia ka huahana ikehu magnetic kiʻekiʻe a me ka coefficient wela haʻahaʻa loa.Hiki ke piʻi ka mahana hana kiʻekiʻe loa i 350 ℃, a ʻaʻole palena ʻole ka mahana wela.Ke piʻi ka mahana hana ma luna o 180 ℃, ʻoi aku ka nui o kāna huahana ikehu magnetic (BHmax) a me ka coercivity (co.
Alnico
ʻO ka Al Ni Co kahi huila i haku ʻia me ka aluminika, nickel, cobalt, hao a me nā mea metala ʻē aʻe.He kiʻekiʻe remanence, haʻahaʻa coercivity, maikaʻi corrosion kū'ē, haʻahaʻa wela coefficient, kiʻekiʻe wela kū'ē, humidity kū'ē, ikaika corrosion kū'ē, 'aʻole maʻalahi i ka oxidize a me ka maikai hana paʻa.Hana ʻia ʻo Sintered al Ni Co e ka pauka metallurgy.Hoʻohana nui ia i nā ʻāpana automotive, instrumentation, motor, electroacoustic, communication, magnetoelectric switch, sensor, aʻo a me ka aerospace.
Mākēneki Rubber Flexible
Ua like loa nā mākēneki hikiwawe me nā magnet i hoʻoheheʻe ʻia akā hana ʻia ma nā ʻāpana palahalaha a me nā lau.He haʻahaʻa kēia mau magnet i ka ikaika magnetic a maʻalahi loa ma muli o nā mea i hoʻohana ʻia i loko o ka pūhui me nā pauka magnetic.Hoʻohana pinepine ʻia ʻo Vinyl i kēia ʻano magnet e like me ka mea hoʻopili.
