Europium (III) oxide
Europium (III) Oxide (EU2O3)yog tshuaj lom neeg tau tshuaj lom neeg thiab cov pa oxygen. Europium oxide muaj lwm lub npe uas yog Europia, Europium trioxexide. Europium oxide muaj xim liab dawb. Europium oxide muaj ob hom qauv sib txawv: cubic thiab monoclinic. Lub cubic teeb tsa Enopium oxide yuav luag tib yam li cov qauv roj magnesium. Europium oxide muaj cov solubrant neglanity hauv dej, tab sis tau yooj yim yaj nyob rau hauv ntxhia acali. Europium oxide yog cov khoom ruaj khov uas muaj melting point ntawm 2350 oc. Europium oxide cov khoom siv ntau zoo li sib nqus, kho qhov muag thiab luminescence cov khoom ua cov khoom siv no tseem ceeb heev. Europium oxide muaj peev xwm nqus noo noo thiab carbon dioxide hauv cov huab cua.
