Application

It is mainly used as YAG crystal additive and nuclear reactor control material. It is also used to make special luminescent glass and infrared absorbing glass. It is also used as glass colorant. It was obtained by the reaction of erbium nitrate or erbium sulfate with alkali by separation and burning. Only Er2O3 is a stable compound. Is the body center cube and monoclinic two structures of powder. The magnetic moment of Er2O3 is also larger, 9.5M.B. Other properties and preparation methods are the same as lanthanide elements. Make pink glass.
