Erbium Oxide
Erbium (III) Oxide, yog synthesized los ntawm lanthanide hlau erbium.Erbium oxide yog lub teeb liab hmoov nyob rau hauv tsos.Nws yog insoluble nyob rau hauv dej, tab sis soluble nyob rau hauv mineral acids.Er2O3 yog hygroscopic thiab yuav nkag tau ya raws thiab CO2 los ntawm huab cua.Nws yog ib qho insoluble thermally ruaj khov Erbium qhov chaw haum rau iav, kho qhov muag, thiab ceramic daim ntaub ntawv.Erbium Oxidetuaj yeem siv los ua cov tshuaj lom neutron flammable rau nuclear roj.
