Metala Samarium | Sm cube | CAS 7440-19-9 | Mea ʻāina laha ʻole

ʻO ka wehewehe pōkole:

Hoʻohana ʻia ʻo Samarium e dope i nā kristal calcium chloride no ka hoʻohana ʻana i nā lasers optical. Hoʻohana ʻia ia i loko o ke aniani infrared a ma ke ʻano he neutron absorber i nā reactors nuklea.

Hiki iā mākou ke hoʻolako i ka maʻemaʻe kiʻekiʻe 99.9%.

ʻO Samarium kahi mea ʻeleʻele ʻeleʻele a he keʻokeʻo keʻokeʻo, palupalu, a me ka metala ductile. He helu hehee kona 1074 °C (1976 °F) a me kahi helu hoʻolapalapa o 1794 °C (3263 °F). ʻIke ʻia ʻo Samarium no kona hiki ke komo i nā neutrons a no kona hoʻohana ʻana i ka hana ʻana i nā magnet samarium-cobalt, i hoʻohana ʻia i nā ʻano noi like ʻole, e komo pū me nā motika a me nā mea hana.
Hana ʻia ka metala Samarium ma o nā ʻano hana like ʻole, me ka electrolysis a me ka hōʻemi wela. Kūʻai maʻamau ia ma ke ʻano o nā ingots, nā koʻokoʻo, nā lau, a i ʻole nā pauka, a hiki ke hana ʻia i nā ʻano ʻē aʻe ma o nā kaʻina hana e like me ka hoʻolei ʻana a i ʻole forging.
Loaʻa i ka Samarium metala kekahi mau noi kūpono, e like me ka hana ʻana i nā catalysts, alloys, a me nā uila, a me ka hana ʻana i nā magnets a me nā mea kūikawā ʻē aʻe. Hoʻohana ʻia ia i ka hana ʻana i nā wahie nuklea a i ka hana ʻana i nā aniani kūikawā a me nā seramika.

Palapala noi

Mākēneki mau: ʻO kekahi o nā noi nui loa o ka samarium ʻo ia ka hana ʻana i nā magnet samarium cobalt (SmCo). Ua ʻike ʻia kēia mau magnet paʻa no ko lākou ikaika magnetic kiʻekiʻe a me ke kūpaʻa wela maikaʻi loa, e hoʻolilo iā lākou i mea kūpono no ka hoʻohana ʻana i nā noi hana kiʻekiʻe e like me nā motika, nā mea hana, a me nā ʻike. He waiwai nui ka SmCo magnet i ka ʻoihana aerospace a me ka pale, kahi koʻikoʻi ka hilinaʻi a me ka hana.
Nukelea Reactors: Hoʻohana ʻia ʻo Samarium ma ke ʻano he neutron absorber i nā reactors nuklea. Hiki iā ia ke hopu i nā neutrons, pēlā e kōkua ai i ka mālama ʻana i ke kaʻina hana fission a mālama i ka paʻa o ka reactor. Hoʻokomo pinepineʻiaʻo Samarium i loko o nā koʻokoʻo mana a me nā mea'ē aʻe, e kōkua ana i ka hana palekana a me ka maikaʻi o nā mea kanu nukili.
Nā Phosphors a me nā kukui: Hoʻohana ʻia nā pūhui Samarium i nā phosphors no nā noi kukui, ʻoi aku ka nui o nā pahu kukui cathode (CRT) a me nā kukui fluorescent. Hiki i nā mea Samarium-doped ke hoʻokuʻu i ka mālamalama i nā nalu nalu kūikawā, a laila e hoʻomaikaʻi ai i ka maikaʻi kala a me ka pono o nā ʻōnaehana kukui. He mea koʻikoʻi kēia noi no ka hoʻomohala ʻana i nā ʻenehana hōʻike kiʻekiʻe a me nā hoʻonā kukui e pono ai ka ikehu.
Agena huikau: Hoʻohana ʻia ka samarium maʻemaʻe ma ke ʻano he mea hoʻohuihui i nā ʻāpana metala like ʻole, ʻoi aku hoʻi i ka hana ʻana i nā mea hoʻokalakupua honua a me nā mea hana kiʻekiʻe. ʻO ka hoʻohui ʻana o ka samarium e hoʻomaikaʻi i nā waiwai mechanical a me ka pale ʻana o ka corrosion o kēia mau alloys, e kūpono ana iā lākou no ka hoʻohana ʻana i nā ʻoihana uila, automotive a me nā aerospace.
