Application
As preparation of metal dysprosium materials, glass, NdFeB permanent magnet additive, also used metal halide, magneto-optical memory material, yttrium iron or yttrium aluminum garnet, atomic energy industry as a nuclear reactor control rod .
Used as raw material for making dysprosium metal, glass, ndfeb permanent magnet additives,
Also used in metal halogen lamp, magnetic light memory material, yttrium iron or yttrium aluminum garnet, atomic energy industry.
Dysprosium oxide can also be used as additives for Ndfeb permanent magnets. Adding about 2 to 3% dysprosium to this magnet can improve its coercivity. Dysprosium was not in great demand in the past, but with the increase in demand for Ndfeb magnets, it has become a necessary addition element, with a grade of 95 to 99. Around 9%, and demand is growing rapidly.
Dysprosium oxide is also used to make dysprosium metal raw materials, glass, ndfeb permanent magnets additives,
Also used in metal halogen lamp, magnetic light memory material, yttrium iron or yttrium aluminum garnet, atomic energy industry.
