Erbium Oxide
Erbium (III) Oxide, yog tsim los ntawm cov hlau lanthanide erbium. Erbium oxide yog hmoov liab dawb zoo li. Nws tsis yaj hauv dej, tab sis yaj hauv cov kua qaub minerals. Er2O3 yog hygroscopic thiab yuav yooj yim nqus cov dej noo thiab CO2 los ntawm huab cua. Nws yog ib qho chaw ruaj khov Erbium uas tsis yaj tau zoo rau kev siv iav, kho qhov muag, thiab cov khoom siv ceramic.Erbium Oxidekuj tseem siv tau ua tshuaj lom neutron uas yooj yim hlawv rau roj nuclear.
