ʻO ka Magic Rare Honua: "Ke aliʻi o nā Magnet mau loa" -Neodymium

Kepanilewa

Neodymium, helu atomic 60, ka nui atomic he 144.24, me kahi kiko'ī o 0.00239% i loko o ka crust, ma ka monazite. Aiaʻehiku mau isotopes o Neodymium ma keʻano: Neodymium 142, 143, 144, 143, 146, 148 a me 158 a me 158 a me 158 aʻo 158 Me ka hānauʻana o Praseodymium, hele maiʻo Neodymium i loko. ʻO ka hōʻeaʻana o ka neodymium i hana i ka pā o ka honua i ka'āina nui a pāʻani i kahi hana koʻikoʻi ma IT.And i ka mākeke uila.

ʻIkeʻole o ka neodymium

ʻO Karl Orvon Welsbach (1858-1929), ka meaʻike o ka neodymium

I ka makahiki 1885, austrian Chemist Carl Orvon Welsbach Carl Aotersmich iʻikeʻiaʻo WiDna. Ua hoʻokaʻawaleʻo ia iā Neodymium a me Praesodymium mai nā kiʻina Neodmymium ma ka hoʻokaʻawaleʻana i ka hoʻoiliʻana, a iʻole ia i hoʻokaʻawaleʻia i loko o 1925.

Mai ka makahiki 1950,ʻoi aku ka nui o ka neodymium medymium (ma luna o 99%) i loaʻa ma ke kaʻina hoʻololi o Monazite. Ua loaʻa iā ia ka mea me ka mea i loaʻa iā ia e ka electrolyzing i kona paʻakai harde. I kēia manawa, ua laweʻia ka hapa nui o ka neodymium mai (Ce, la, pr) co3f ma belast ʻO ka hoʻololiʻana i ka hoʻomaʻemaʻeʻana i ka hoʻomaʻemaʻe kiʻekiʻe (maʻamau> 99.99%)

Maol Meodymium

ʻO ka leʻaleʻa Meodymium heʻoluʻolu haʻahaʻa browtalic, melting point o 1024 ° C, a me nā paramagnetism. ʻO Neoodymium kekahi o nā mea ikaika loa o ka honua ikaika loa, nā mea eʻoi aku ka wikiwiki a me nāʻeleʻele i ka lewa a laila e hōʻike ana i ka maniko. No laila,ʻo keʻano neodymium e like me ka nui o hoʻokahi centimeter i loko o hoʻokahi makahiki i loko o hoʻokahi makahiki. E hana mālie ia i ka wai anuanu a wikiwiki i ka wai wela.

Hoʻomonopono Hoʻololi neodymium i ka uila uila

Hoʻopuka:

1s2 2S2 3002 3s22 3006 4sp6 500 4P6 6Ds2 4D4

ʻO ka hana Laser o Neodymium i hoʻokumuʻia e ka hoʻololiʻana o 4f Orbital Electrons ma waena o nā pae likeʻole. Hoʻohana nuiʻia kēia mea Laser ma ke kamaʻilioʻana, ka mālamaʻana i kaʻoihana

Ke noiʻana o Neodymium

ʻO ka mea hoʻohana nui loa o ka neodymium ka mea e pili ana i nā mea magnet mau magnet. Ua kapaʻiaʻo NDFEB magnet "ʻo ke aliʻi o nā magnenes mau" ma muli o kāna huahana nui kiʻekiʻe. Ua hoʻohana nuiʻia ia ma nā mea uila, nā mīkini a me nāʻoihana'ē aʻe no kāna hana maikaʻi loa. ʻO Francis Wall, he kumuwaiwai o ka hoʻohanaʻana i ke kulaʻo Cumberlandʻo Cumberland, he University of Firstros of China

Neodymium magnet ma ka pā paʻakikī

Hiki ke hoʻohanaʻiaʻo Neoodymium i nā cubramics Hoʻohana pūʻia me Praseodymium e hana i nā goggles no nā aniani aniani.

Hoʻohui i ka 1.5% ~ 2.5% Ua hiki i ka Neodymium Oxide i ka hana nui, a he ākea ka palekana o ka malono, a he ākea ka palekana o Aaluni

I ka mālama lapaʻau,ʻo Nano Ytrium Anuminum Garnet Paser i hanaʻia me Nano Neodymium Oxide a weheʻole i nā hōʻeha hōʻeha a iʻole nā ​​hōʻeha o nā pohō.

Hanaʻia nā aniani neodymium ma ka hoʻohuiʻana iā Neodymium Oxide i loko o ke aniani polū. Hōʻike pinepineʻiaʻo Lavender i ke aniani Neodymium ma lalo o ka lā a iʻole ke kukui kukui, akāʻikeʻia ke kukui kukui ma lalo o ka maʻi maʻi maʻi maʻi. Hiki ke hoʻohanaʻiaʻo Neoodymium i ke kala kala kala kalaʻana o ke aniani e like me ka violet

Nā aniani Neodymium

Me ka hoʻolālāʻana o kaʻepekema a me kaʻenehana a me ka hoʻonuiʻana a me ka hoʻonuiʻana o kaʻepekemaʻoihana a me kaʻenehana,ʻo Neodymium kahi wahi ākea
