ʻO ka hoʻohana nui o scandium

ʻO ka hoʻohana nui o scandium

 sc

Ka hoohana ana oscandium(ʻo ia ka mea hana nui, ʻaʻole no ka doping) i hoʻopaʻa ʻia i kahi ala mālamalama loa, ʻaʻole ia he mea hoʻonui ke kapa ʻia ʻo ia ke Keiki o ka mālamalama.

 

1. Ke kukui sodium Scandium

ʻO ka mea kaua kilokilo mua o ka scandium i kapa ʻia ʻo scandium sodium lamp, hiki ke hoʻohana ʻia e lawe i ka mālamalama i nā tausani o nā hale. He kumu kukui uila halide metala kēia: hoʻokomo ʻia ka sodium iodide a me scandium iodide i loko o ka puʻupuʻu, a hoʻohui ʻia ka scandium a me ka sodium foil. I ka hoʻokuʻu ʻana o ka volta kiʻekiʻe, hoʻokuʻu nā ion scandium a me nā ion sodium i ko lākou mau hawewe hoʻokuʻu ʻana o ka māmā. ʻO nā laina spectral o ka sodium ʻelua mau laina melemele kaulana, 589.0nm a me 589.6nm, aʻo nā laina spectral he pūʻulu kokoke i nā ultraviolet a me nā kukui uliuli mai 361.3-424.7nm. Ke hoʻokō nei lākou i kekahi i kekahi, ʻo ke kala holoʻokoʻa i hana ʻia he kukui keʻokeʻo. No ka mea, loaʻa i nā kukui sodium scandium nā hiʻohiʻona o ka maikaʻi luminous kiʻekiʻe, ke kala kukui maikaʻi, ka mālama ʻana i ka mana, ke ola lōʻihi o ka lawelawe ʻana, a me ka ikaika haʻihaʻi o ka noe i hiki ke hoʻohana nui ʻia no nā kiʻi kīwī, nā ʻāpana, nā wahi haʻuki, a me nā kukui alanui, a ua ʻike ʻia ʻo ke kolu o ka hanauna kumu kukui. Ma Kina, hoʻolaha ʻia kēia ʻano kukui ma ke ʻano he ʻenehana hou, ʻoiai ma kekahi mau ʻāina i kūkulu ʻia, ua hoʻohana nui ʻia kēia ʻano kukui e like me ka hoʻomaka ʻana o nā makahiki 1980.

 

2. Nā pūnaewele photovoltaic solar

ʻO ka lua o ka mea hoʻokalakupua o scandium he solar photovoltaic cell, hiki ke hōʻiliʻili i ka mālamalama i hoʻopuehu ʻia ma ka honua a hoʻohuli iā ia i uila e hoʻokele i ke kaiāulu kanaka. I loko o ka metala insulator semiconductor silicon solar cell a me solar cell, ʻo ia ka mea ʻoi loa ka metala pale.

 

3. γ Puka uila

ʻO ke kolu o ka mea hana kilokilo o scandium i kapa ʻia ʻo γ He kumu kukuna, hiki i kēia mea kilokilo ke ʻālohilohi i kona iho, akā ʻaʻole hiki ke loaʻa kēia ʻano kukui e ka maka ʻōlohelohe, he kahe photon kiʻekiʻe. Lawe pinepine mākou i ka 45 Sc mai nā minela, ʻo ia wale nō ka isotope maoli o scandium. Loaʻa i kēlā me kēia 45 Sc nucleus he 21 protons a me 24 neutrons. Hiki ke hoʻohana ʻia ʻo 46Sc, kahi isotope radioactive artificial, ma ke ʻano he kumu γ Radiation a i ʻole tracer atoms hiki ke hoʻohana ʻia no ka radiotherapy o nā maʻi maʻi ʻino. Aia kekahi mau noi e like me ka scandium garnet lasers, fluorinated glass infrared optical fiber, a me nā pahu kukui cathode i uhi ʻia me ka scandium ma nā televise. Me he mea lā ua hānau ʻia ka scandium me ka mālamalama.

 

4. ʻO nā mea hoʻonani kilokilo

ʻO ka mea i ʻōlelo ʻia ma luna nei kekahi mau noi o ka scandium, akā ma muli o kāna kumukūʻai kiʻekiʻe a me nā kumu kūʻai, ʻaʻole i hoʻohana ʻia ka nui o nā scandium a me nā pūhui scandium i nā huahana ʻoihana, me ka hoʻohana ʻana i kahi ʻāpana lahilahi o ka foil e like me ke kukui kukui. Ma nā kula ʻē aʻe, hoʻohana ʻia nā pūhui Hetong e like me nā mea hoʻonaninani, e like me ka paʻakai, ke kō, a me ka monosodium glutamate i nā lima o nā chefs. Me ka liʻiliʻi liʻiliʻi, hiki iā lākou ke hana i ka hoʻopau ʻana.

 

5. Ka hopena i nā kānaka

ʻAʻole maopopo i kēia manawa inā he mea koʻikoʻi ka scandium no ke kanaka. Loaʻa ka Scandium i loko o ke kino kanaka. Manaʻo ʻia he carcinogenicity. Hiki i ka Scandium ke hana i nā paʻakikī me nā hui 8-māmā, hiki ke hoʻohana ʻia no ka nānā ʻana i ka scandium. Hiki ke hoʻohana ʻia ka neutron radiometric analysis e hoʻoholo i ka helu ma lalo o ng/g.
