Nano europium oxide Eu2O3

Inoa mea kūʻai:Europium oxideEu2O3

Hōʻike: 50-100nm, 100-200nm

Waihoʻoluʻu: ʻulaʻula keʻokeʻo keʻokeʻo

(He ʻokoʻa ka nui o nā ʻāpana a me nā kala)

ʻO ke ʻano aniani: cubic

Ka helu hehee: 2350 ℃

Māmā nui: 0.66 g/cm3

ʻĀpana ili kikoʻī: 5-10m2/gEuropium oxide, ka helu heheʻe 2350 ℃, hiki ʻole ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i loko o ka waika, ka nui 7.42g/cm3, ka hoʻoheheʻe kemika Eu2O3;Hōʻike pinepine ʻia e like me ka pauka keʻokeʻo a ʻulaʻula iki paha.Hiki ke hoʻoheheʻe pū me ka mahu, he alkaline, ʻawaʻawa, a hoʻonāukiuki i ka maka, ka ʻōpū hanu, a me ka ʻili.Hiki iā ia ke komo i ka carbon dioxide i ka lewa a hana i nā paʻakai hiki ke hoʻoheheʻe ʻia i ka wai me nā ʻakika inorganic.

Hoʻohana nui ʻia ʻo Europium i ka hana ʻana i nā mea mana reactor a me nā mea pale neutron.Ma ke ʻano he pauka fluorescent no nā kīwī kala, loaʻa iā ia nā noi koʻikoʻi i nā mea laser europium (Eu) a me nā ʻoihana ikehu atomic.ʻO Europium kekahi o nā mea laʻa loa o ka honua.ʻO 1.1 ppm wale nō kona ʻike ma ka Honua.He mea palupalu, ʻālohilohi, kila hina hina me ka ductility ikaika a me ka malleability, ʻo ia hoʻi, hiki ke hana ʻia i nā ʻano like ʻole.Ua like kona ʻano me ke kēpau, akā ua ʻoi aku ke kaumaha.

Kahua noi:

 1. Hoʻohana ʻia e like me ka ʻulaʻula fluorescent pauka mea hoʻāla no nā kīwī kala a me ka pauka fluorescent no nā kukui mercury kiʻekiʻe.

 2. Hoʻohana ʻia no ka hana ʻana i nā dyes, nā mea hoʻoheheʻe vulcanization, lāʻau lapaʻau, pesticide fungicides, amino resins, ethylenediamine urea formaldehyde resins, metala chelating agents EDTA, etc.

 3. Hoʻohana ʻia e like me ka solvent no ka fibrin, etc.
