Xim: Paj yeeb Dawb Dawb
(Qhov sib txawv particle loj thiab xim yuav txawv)
Crystal form: kub
Melting point: 2350 ℃
Qhov ceev: 0.66 g / cm3
Qhov chaw tshwj xeeb: 5-10m2 / gEuropium oxide, melting point 2350 ℃, insoluble nyob rau hauv dej, soluble nyob rau hauv acid, ceev 7.42g / cm3, tshuaj formula Eu2O3; Feem ntau tshwm li dawb los yog me ntsis liab hmoov. Nws tuaj yeem evaporate ua ke nrog chav, yog alkaline, tshuaj lom, thiab ua rau lub qhov muag, ua pa, thiab tawv nqaij. Nws tuaj yeem nqus cov pa roj carbon dioxide hauv huab cua thiab tsim cov dej-soluble ntsev nrog inorganic acids.
Europium yog dav siv nyob rau hauv kev tsim cov reactor tswj cov ntaub ntawv thiab cov ntaub ntawv tiv thaiv neutron. Raws li cov hmoov fluorescent rau cov xim TV, nws muaj cov ntawv thov tseem ceeb hauv europium (Eu) cov ntaub ntawv laser thiab atomic zog industries. Europium yog ib qho ntawm cov khoom tsis tshua muaj hauv ntiaj teb. Nws cov ntsiab lus hauv ntiaj teb tsuas yog 1.1 ppm. Nws yog mos, ci, steel grey hlau uas muaj zog ductility thiab malleability, uas txhais tau hais tias nws tuaj yeem ua tiav rau hauv ntau yam duab. Nws zoo nkaus li thiab zoo li txhuas, tab sis nws hnyav dua me ntsis.
1. Siv los ua cov hmoov fluorescent liab activator rau cov xim TV thiab cov hmoov fluorescent rau cov teeb pom kev siab mercury.
2. Siv los ua dyes, roj hmab vulcanization accelerators, tshuaj, tshuaj tua kab fungicides, amino resins, ethylenediamine urea formaldehyde resins, hlau chelating agents EDTA, thiab lwm yam.
3. Siv los ua cov kuab tshuaj rau fibrin, thiab lwm yam.
