Praesoodmiumumʻo ke kolu o ka mea nui loa ma keʻano he nui o ka papa hana o ka manawa o ka manawa o ka cemika, me ka nui o ka nui o 9.5 pPMKipuka, yttrium,Lanthanum, aScandium. ^. ʻO ia ka hapalima nui loa i nā'āina nui. Akā like me kona inoa,Praesoodmiumumhe lālā maʻalahi a maikaʻiʻole paha o kaʻohanaʻohana.
Cf Auer / Welsach iʻike iā Praseodymium i ka makahiki 1885.
I loko o 1751, ua loaʻa iā ia ka mineralogist Axic i loaʻa iā Axel Fredik Crredtedt i loaʻa i kahi minerlent kaumaha ma kaʻaoʻao o Bastn, ma hope ke inoaʻia ma hope. He kanakolukumamākahi mau makahiki ma hope mai I ka makahiki 1803, ma hope o ka mele o Singer, ua hoʻi hou maiʻo ia i ka Pepa Ment oke, a holo lākou iʻelua mau makahiki i hala. Ua hoʻokaʻawaleʻiaʻo Ceria kūʻokoʻa iā Martin Heinrich KlaPoth ma Kelemānia.
Ma waena o 1839 a me 1843, SUDED SURGEON a me Chemist Carl Gustaf i loaʻa i kēlāKaniʻo Turidehe hui o nā orides. Ua hoʻokaʻawaleʻo ia iʻelua o nā bipiʻelua e kāhea ana iā Heymia a'Isoʻo. Ua hoʻokaʻawaleʻo ia i kaCIEIL KePanihoʻohālikelike e ka holoʻana i ka lewa, a laila moeʻia me ka dilric me kahi dutid e loaʻa ai ka bipi. ʻO nā metals e hoʻokumu i kēia mau bipiLanthanumaPraesoodmiumum.
I ka makahiki 1885, CF Auter von Welsbach, kahi Austrian e hana ana i ka paʻakaiʻo Chorium Cribum. Ua kapaʻia kekahi "Praereodymium", e hele mai ana mai ka hua'ōlelo Helene, e pili ana i ka'ōnaehana'ōmaʻomaʻoʻo ka praseodymium paʻakai; ʻO ka mea'ē aʻe i kapaʻiaʻo "Neodymium". ʻO ka hoʻokaʻawale kūʻokoʻa o nā'āpana "conjoid mau māhoe" i hiki iā lākou ke hōʻike kūʻokoʻa i kā lākou mau talena kūʻokoʻa.
ʻO ka melala gula,ʻulaʻula, palupalu a me nā ducile. ʻO Praseodymium kahiʻano hexagonalʻo ia i keʻano o ka mahana o ka lumi. Uaʻoi aku ka ikaika o ke kū'ēʻana i ka ea ma mua o ka lanthanum, cerum, neodymium
E like me ka hapa nuiNā Kūlana Honua,ʻo Praseodymium ka mea nui loa e hana ai i kahi kūlana + 3 oxidation,ʻo ia wale nō keʻano o nā hopena kūponoʻole. Nohoʻo Praesodymium i kahi kūlana + 4 inidation ma kekahi mau pupu paʻa iʻikeʻia, a ma lalo o nā kūlana hoʻokaʻawale o Matrix, hiki iā ia ke hōʻea i kahi kūlana'ē aʻe.
ʻO ka braseodymium i loko o ka mālamaʻana i kaʻoihana, a he nui nā hoʻohanaʻana o kaʻoihana nui o Praseodymium e pili ana i kona hiki ke kānana māmā māmā i nā kukui uila.

Ua hoʻonohonohoʻia nā electrons 59 o Praseodymium e [xe] 4f36s2. Hiki ke hoʻohanaʻia nā mea kūʻai aku,ʻelima mau electrons e like me Valence Electron, akāʻo ka hoʻohanaʻana o nā electrol a pau e pono ai nā electrols i nā elemakule. ʻO ka maʻamau,ʻo Praseodymium wale nō e hoʻopili wale iʻekolu aʻehā paha uila i loko o kāna mau pūpū. ʻO Praseodymium ka mea maʻamauʻo Lanthandel Electhanade me kahi hoʻonohonoho uila uila e hoʻokō ai i ke kumu o ka mea e pono ai. Loaʻa i kona mau orbital 4f i lalo o nā pae haʻahaʻa haʻahaʻa ma mua o ka 5d Orbital,ʻaʻole i pili i ka lanthanum a hikiʻole ke pale aku i ka halaʻana o ka lasthanum Eia nō naʻe, ua hōʻikeʻo Praseodymium i kahi [xe] 4f25d16s2 e like me nā mea'ē aʻe
E like me ka hapa nui o nā mea maʻamau Lanthankymium, hoʻohana pinepineʻia nā electron e like me Valence Binder. Eia nō naʻe, hiki i ka Praseodymium ke hoʻomau e nalowale i kaʻehā a i kekahi manawa e hiki ai i keʻano o ka mea kūʻai aku.
Praseodymium a me nā mea āpau a pau loa (koe wale nōLanthanum, 'PukuleloaLuutium,ʻaʻole i loaʻa nā electrons 4f iʻoleʻia)ʻo Paramagnetism ma ka mahana o ka lumi. ʻAʻole e like me nā medit gever i nā metala e hōʻike ana i ke antiferrometic a iʻole ferromagnetic i nā mahana haʻahaʻa
Ke noiʻana o Praseodymium
Hoʻohana nuiʻiaʻo Praseodymium i keʻano o nā'ōiwi i huiʻia, e like me ka hoʻomaʻemaʻeʻana i nā mea metala, a pēlā aku.Praseodymium neodymiumʻo ia ka mea like a paʻakikī loa e hoʻokaʻawale i nā'āpana o nā'āpana o ka honua Hoʻohana pinepine ka mea hanaʻoihana i nāʻano extraction a me ka hoʻololiʻana i ka hoʻololiʻana. Inā hoʻohanaʻia lākou ma nā pākuʻi ma keʻano o ka nui o ka inoa uku me ka hapanui o ka Neodymium, hiki ke hoʻohanaʻia kā lākouʻano.
Alodymium alodymium alloymium alloymium(Praseodymium neodymium nevymium)ua lilo i huahana kūʻokoʻa, hiki ke hoʻohanaʻia e like me nā meaʻelua magnet mau a me kahi hoʻololi hoʻololi no nā mea kilokilo non-ferrous. ʻO ka hana, ke koho a me ke kūpaʻaʻana o ka petroleum e hoʻopili i ka catalyst e hoʻopiliʻia e ka hoʻohuiʻana o Praseodymium i ka maʻi Braseodymium E like me kahi hoʻohui hoʻohui hoʻohui, hoʻohui i ka hoʻonuiʻana o Praseodymium Neodymium i ka polytetraflushethyyyyyyyyyyyyyyyyyyyyyyyyyyySheetLitheth
Ka hiʻuʻonaʻO nā kumumanaʻo mau magnet mau loaʻo ia ka mahina nui loa o nā noi o ka Honua. ʻAʻole wale ka praeodymium,ʻaʻole ia he mea nui e like me ka mea nui magnet mau, akā he mea maikaʻi loa ia e hiki ai ke hoʻomaikaʻi i nā waiwai magines. ʻO ka hoʻohuiʻana i kahi nui kūpono o ka praseodymium hiki ke hoʻomaikaʻi maikaʻi i ka hana o nā mea nui. Hiki iā ia ke hoʻomaikaʻi hou i ka hana antioxadant hoʻokō (Air Cortorionies of Magnetos, a ua hana paʻaʻia ma nāʻaoʻao uila uila.
Hiki ke hoʻohanaʻiaʻo Praseodymium i nā mea hoʻonaninani a me nā mea hoʻohui. Keʻike nei mākou a pau,ʻo Cerium Cerul e pili ana i ka pwder powder e pili ana i ka waihoʻoluʻu i ka wai uila Uaʻike nā kānaka ua loaʻa nā praseodymium maikaʻi i nā waiwai kūpono. ʻO Rare ka Honua i ka pauka eʻikeʻiaʻo Praseoodymium i'ulaʻulaʻula,ʻaʻole iʻikeʻia kaʻulaʻula Ua hoʻohanaʻiaʻo Praeaodymium i kahi mea e like me ka mea i hana houʻia e hana i nā huila e hana ana i nā huila e loaʻa ana ka praseodymium. Hoʻohālikelikeʻia me ke keʻokeʻo ALUMIE, pono a me ke kūpaʻa a me ka nui o ka loaʻaʻana o ka carbor carbon I mea e hōʻemi ai i nā kumukūʻai,ʻo Praseodymium Neodymium nā mea i hana pinepineʻia e like me nā mea i hala aku nei, he hewa ka inoaʻo Praseodymium ma mua.
Ua hoʻohanaʻia nā crystate crystals me ka praseodymium i hoʻohanaʻia e lohi i nā pulu kukui iʻelua mau minuke i hoʻokahi kekona.
Hoʻohuiʻiaʻo Praseodymium Emdide i ka silikaʻo Zirconium Silita e hoʻohuli i ka melemele a hiki ke hoʻohanaʻia e like me ke melemele curseodymium. Ua manaʻoʻiaʻo Praseodymium
Hoʻohanaʻia ka Praeodymium i kahi aniani aniani, me nā kala waiwai a me nā mākeke nui. Hiki ke hana i nā huahana Green Green Green Green me nā kukuiʻulaʻula a me nā meaʻalaʻala, hiki ke hoʻohanaʻia e hana i nā kānana Green a me nā kiʻiʻoniʻoni. Hoʻohui i ka praseodymium oxide a me ka ceriumx e hiki ke hoʻohanaʻia i ke aniani e hiki ke hoʻohanaʻia e like me nā goggles no ka ulding. Hiki ke hoʻohanaʻiaʻo Praseodymium sulfide e like me ka color plastic uliuli.
