Txoj kev npaj ntawm europium oxide:
Ntxiv hydrochloric acid rau europium-nplua nuj tsawg lub ntiaj teb oxide, yaj thiab lim kom tau txais cov tshuaj EuCl2. Ntxiv cov tshuaj EuCl2 rau cov neeg sawv cev sib xyaw thiab muab rho tawm hauv cov khoom siv ultrasonic extraction kom tau txais cov EuCl2 refined kua. Ntxiv cov EuCl2 refined kua rau lub anode ntawm lub electrochemical reactor oxidize lub divalent europium ions rau hauv trivalent europium ions los tsim EuCl3 refined kua. Ntxiv adsorbent rau EuCl3 refined kua. Tom qab adsorption thiab tshem tawm cov impurities, cov khoom thiab cov kua yog sib cais kom tau ib tug high-purity EuCl3 tov. Ammonium carbonate yog ntxiv kom tau txais europium carbonate nag lossis daus, pom, ntau kauj ruam purification, thiab thaum kawg los ntawm High-purity europium oxide yog tau los ntawm kub kub kub, ntxuav thiab ziab.
Kev siv cov europium oxide:
Europium oxide tuaj yeem siv los ua phosphor raw khoom. Nws yog siv nyob rau hauv stimulated emission phosphors rau cov xim cathode ray tubes, xim TV duab tubes, lub computer saib, peb-primary fluorescent teeb thiab tshiab ntev afterglow qhia, raws li zoo raws li tshiab X-ray kev kuaj mob systems.
Europium oxide kuj tuaj yeem siv los ua cov xim lo ntsiab muag thiab cov lim dej kho qhov muag. Chips thiab sib nqus npuas cia khoom; nws kuj yog ib qho tseem ceeb heev nyob rau hauv cov ntaub ntawv tswj, shielding cov ntaub ntawv thiab structural ntaub ntawv ntawm atomic reactors.
Nws yog siv los ua cov xim hauv kev lag luam iav los ua cov iav txiv kab ntxwv-liab, los tsim cov iav hluav taws xob, thiab ua ib qho ntxiv rau quartz optical fibers. Europium oxide yog siv los ua tus activator rau ntau phosphor. Piv txwv li, Eu3+ yog siv los qhib Y2O3 lossis Y2O2S hauv cov raj xim xim, thiab ua kom YVO4 nrog lub teeb hluav taws xob siab mercury.
Hauv kev lag luam nuclear, europium oxide yog siv los ua cov khoom siv neutron. Vim tias europium atoms tuaj yeem nqus tau ntau dua neutrons dua li lwm cov khoom, nws feem ntau siv los ua cov khoom siv neutron-absorbing hauv atomic reactors.
Tsis tas li ntawd, europium oxide kuj tuaj yeem siv los ua cov kuab tshuaj fibrin, thiab lwm yam, thiab tseem tuaj yeem siv los npaj cov dyes, roj hmab vulcanization accelerators, tshuaj, tshuaj tua kab thiab fungicides, amino resins, ethylenediamine urea-formaldehyde resin, hlau chelating tus neeg saib xyuas EDTA. , lwm.
