Hōʻike kikoʻī
LanthanumHe mea kemika me ka hōʻailona La a me ka helu ʻātoma 57. No ka hui o nā mea i kapa ʻia ʻo ka lanthanides, ʻo ia ka pūʻulu o 15 mau mea metala i loaʻa i ka pākaukau manawa ma lalo o nā metala hoʻololi.
Ua ʻike mua ʻia ʻo Lanthanum i ka makahiki 1839 e ka mea loea Suedena ʻo Carl Gustaf Mosander i kona hoʻokaʻawale ʻana iā ia mai ka cerium nitrate. ʻO kona inoa mai ka huaʻōlelo Helene "lanthanein," ʻo ia hoʻi "e moe huna" ʻoiai ʻike pinepine ʻia ka lanthanum i hui pū ʻia me nā mea ʻē aʻe i loko o nā minerala like ʻole.
Ma kona ʻano maʻemaʻe, ʻo ka lanthanum he metala palupalu a keʻokeʻo keʻokeʻo i hoʻoikaika nui a maʻalahi hoʻi i ka ea. ʻO ia kekahi o ka liʻiliʻi loa o nā mea lanthanide akā ʻoi aku ka maʻamau ma mua o nā mea e like me ke gula a i ʻole platinum.
Loaʻa mua ʻia ka Lanthanum mai nā minela e like me ka monazite a me ka bastnäsite, kahi i hui pū ʻia me nā mea o ka honua.
Loaʻa i ka Lanthanum nā waiwai kaulana e hoʻohana pono ai i nā noi like ʻole. He wahi heheʻe kiʻekiʻe kona a hiki ke kū i nā wela kiʻekiʻe, kūpono ia no ka hoʻohana ʻana i nā kukui kalapona kalapona kiʻekiʻe no nā mea hana kiʻiʻoniʻoni, nā kukui studio, a me nā noi ʻē aʻe e koi ana i nā kumu kukui ikaika. Hoʻohana ʻia ia i ka hana ʻana i nā pahu kukui cathode (CRTs) no nā kīwī a me nā mea nānā kamepiula.
Hoʻohui ʻia, hoʻohana ʻia ka lanthanum ma ke kahua o ka catalysis, kahi e hiki ai ke hoʻonui i ka hana o kekahi mau catalysts i hoʻohana ʻia i nā hopena kemika. Ua loaʻa pū kekahi i nā noi i ka hana ʻana i nā ʻeke uila kaʻa hybrid, nā lens optical, a ma ke ʻano he mea hoʻohui i ke aniani a me nā mea seramika e hoʻomaikaʻi ai i ko lākou ikaika a me ke kūʻē ʻana i ka haki.
Hoʻohana ʻia nā pūhui Lanthanum i ka lāʻau lapaʻau pū kekahi. ʻO ka Lanthanum carbonate, no ka laʻana, hiki ke kuhikuhi ʻia ma ke ʻano he phosphate binder e kōkua i ka mālama ʻana i nā kiʻekiʻe phosphate kiʻekiʻe i loko o ke koko o nā maʻi me ka maʻi maʻi. Hoʻohana ia ma ka hoʻopaʻa ʻana i ka phosphate i loko o ka digestive tract, pale i kona komo ʻana i loko o ke kahe koko.
ʻO ka holoʻokoʻa, ʻo ka lanthanum kahi mea maʻalahi me ka nui o nā noi i nā ʻoihana e like me ke kukui, uila, catalysis, ʻepekema waiwai, a me nā lāʻau lapaʻau. ʻO kāna mau waiwai kūʻokoʻa a me kona ʻano hana e waiwai ai i nā ʻano ʻenehana a me nā ʻano ʻepekema.
Palapala noi
He nui nā noi o Lanthanum ma nā ʻoihana like ʻole ma muli o kāna mau waiwai kūʻokoʻa:
Ke kukui:Hoʻohana ʻia ʻo Lanthanum i ka hana ʻana i nā kukui arc carbon, kahi i hoʻohana ʻia i nā projectors film, nā kukui studio, a me nā kukui hulina. Hoʻopuka kēia mau kukui i kahi kukui māmā a ikaika, e kūpono ana ia no nā noi e koi ana i ka hoʻomālamalama kiʻekiʻe.
Mea uila:Hoʻohana ʻia ʻo Lanthanum i ka hana ʻana i nā pahu kukui cathode (CRTs) no nā kīwī a me nā mea nānā kamepiula. Hoʻohana nā CRT i kahi kukuna electron e hana i nā kiʻi ma ka pale, a hoʻohana ʻia ka lanthanum i ka pū electron o kēia mau mea hana.
Nā ʻōhua:Hoʻohana ʻia ʻo Lanthanum i ka hana ʻana i nā pihi nickel-metal hydride (NiMH), i hoʻohana mau ʻia i nā kaʻa uila hybrid (HEV). ʻO nā huila Lanthanum-nickel kahi ʻāpana o ka electrode maikaʻi ʻole o ka pākaukau, e hāʻawi ana i kāna hana a me ka hiki.
Optics:Hoʻohana ʻia ʻo Lanthanum i ka hana ʻana i nā lens optical kūikawā a me nā aniani. Hiki iā ia ke hoʻonui i ka refractive index a me ka hoʻopuehu ʻana o kēia mau mea, e hoʻohana pono iā lākou i nā noi e like me nā lens kamera a me nā telescopes.
Nā mea hoʻoheheʻe kaʻa:Hoʻohana ʻia ʻo Lanthanum ma ke ʻano he catalyst i nā ʻōnaehana exhaust o nā kaʻa. Kōkua ia i ka hoʻololi ʻana i nā mea hoʻoheheʻe ʻino, e like me ka nitrogen oxides (NOx), carbon monoxide (CO), a me ka hydrocarbons (HC), i mau mea ʻino.
Keaniani a me ka keramika:Hoʻohana ʻia ka Lanthanum oxide ma ke ʻano he mea hoʻohui i ka hana ʻana i nā aniani a me nā mea seramika. Hāʻawi ia i ka wela maikaʻi a me nā waiwai kūʻē i ka haʻalulu, e hana i nā huahana hope i ʻoi aku ka lōʻihi a me ka liʻiliʻi o ka pōʻino.
Nā lāʻau lapaʻau:Hoʻohana ʻia nā pūhui Lanthanum, e like me ka lanthanum carbonate, i ka lāʻau lapaʻau ma ke ʻano he phosphate binders i ka mālama ʻana i nā maʻi me ka maʻi maʻi maʻi maʻi. Hoʻopili kēia mau mea i ka phosphate i loko o ka digestive tract, pale i kona komo ʻana i loko o ke kahe koko.
Metallurgy: Hiki ke hoʻohui ʻia ʻo Lanthanum i kekahi mau alloys e hoʻomaikaʻi i ko lākou ikaika a me ke kūpaʻa wela kiʻekiʻe. Hoʻohana ʻia ia i ka hana ʻana i nā metala kūikawā a me nā ʻāpana no nā noi e like me ka aerospace a me nā mīkini hana kiʻekiʻe.
He mau laʻana wale nō kēia o nā noi lanthanum. ʻO kāna mau waiwai kūʻokoʻa he mea waiwai ia i nā ʻoihana like ʻole, e hāʻawi ana i ka holomua o ka ʻenehana, ka ikehu, ka optics, a me ka mālama olakino.
