Dysprosium oxide is an additive element of yttrium iron and yttrium aluminum garnet, which can be used as a control material for nuclear reactors.
Dysprosium oxide is used to manufacture new dysprosium lamps with high brightness and good light color. Due to its cathode emission capability, it can also be used as an anode coating.
Dysprosium oxide also as raw material for metal dysprosium, glass, NdFeB permanent magnet additive, magneto-optical memory material.
