Nano europium oxide Eu2O3

Dzina la malonda:Europium oxideEu2O3

Kufotokozera: 50-100nm, 100-200nm

Mtundu: Pinki White White

(Kukula kosiyanasiyana ndi mitundu ingasiyane)

Mawonekedwe a Crystal: cubic

Malo osungunuka: 2350 ℃

Kuchulukana kwakukulu: 0.66 g/cm3

Malo enieni: 5-10m2/gEuropium oxide, malo osungunuka 2350 ℃, osasungunuka m'madzi, osungunuka mu asidi, kachulukidwe 7.42g/cm3, formula ya mankhwala Eu2O3; Nthawi zambiri amawoneka ngati ufa woyera kapena wapinki pang'ono. Zitha kusanduka nthunzi pamodzi ndi nthunzi, zimakhala zamchere, zapoizoni, komanso zimakwiyitsa m'maso, m'njira yopuma komanso pakhungu. Imatha kuyamwa mpweya woipa mumlengalenga ndikupanga mchere wosungunuka m'madzi wokhala ndi ma inorganic acid.

Europium imagwiritsidwa ntchito kwambiri popanga zida zowongolera riyakitala ndi zida zoteteza manyutroni. Monga fulorosenti ufa wa ma televizioni amtundu, uli ndi ntchito zofunika mu europium (Eu) zipangizo za laser ndi mafakitale a mphamvu ya atomiki. Europium ndi imodzi mwazinthu zomwe zimasowa kwambiri padziko lapansi. Zomwe zili Padziko Lapansi ndi 1.1 ppm chabe. Ndi chitsulo chofewa, chonyezimira, chachitsulo chotuwa chokhala ndi ductility cholimba komanso chosasunthika, kutanthauza kuti chikhoza kusinthidwa kukhala mawonekedwe osiyanasiyana. Imawoneka komanso imamveka ngati mtovu, koma ndi yolemera pang'ono.

Munda wa ntchito:

 1. Amagwiritsidwa ntchito ngati choyambitsa ufa chofiira cha fulorosenti cha ma televizioni amtundu ndi ufa wa fulorosenti kwa nyali zamphamvu kwambiri za mercury.

 2. Amagwiritsidwa ntchito popanga utoto, mphira vulcanization accelerators, mankhwala, fungicides mankhwala, amino resins, ethylenediamine urea formaldehyde resins, zitsulo chelating agents EDTA, etc.

 3. Ntchito monga zosungunulira fibrin, etc.
