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 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 hoʻohālikelike 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 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'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.
