Detail
Uses: used as the raw material for preparing metal dysprosium, glass and neodymium iron boron permanent magnet, and also used in metal halogen lamp, magneto optical memory material, yttrium iron or yttrium aluminum garnet, atomic energy industry. Dysprosium oxide can also be used as additive of NdFeB permanent magnet, add about 2~3% of dysprosium in this magnet, can improve the coercive force, there is not much demand for dysprosium in the past, but with the increasing demand of NdFeB magnets, it becomes necessary to add elements, must be in 95 ~ 99 grade. 9%, the demand is also rapidly increasing. Dysprosium oxide is also used as a raw material for preparing dysprosium metal, glass and neodymium iron boron permanent magnet, and also used in metal halogen lamp, magneto optical memory material, yttrium iron or yttrium aluminum garnet, atomic energy industry. .
