    Erbium oxide

    Erbium(III) oxide, waxa laga soo saaray birta lanthanide erbium. Erbium oxide waa budo casaan khafiif ah muuqaal ahaan. Waa mid aan lagu milmi karin biyaha, laakiin waxay ku milmaan asiidhyada macdanta. Er2O3 waa hygroscopic waxayna si sahal ah u nuugi doontaa qoyaanka iyo CO2 jawiga. Waa il Erbium oo heerkul ahaan deggan oo aad u aan milmi karin oo ku habboon codsiyada muraayadaha, indhaha, iyo dhoobada.Erbium oxideWaxa kale oo loo isticmaali karaa sidii sunta neutron-ka oo ololaysa shidaalka nukliyeerka.
