Rare Earth Dysprosium Oxide Powder From China with High Purity
Uses: used for the preparation of metal dysprosium raw materials, glass, NdFeB permanent magnet additives, but also for metal halide lamp, magneto-optical memory material, yttrium iron or yttrium aluminum garnet, atomic energy industry. Dysprosium oxide can also be used as NdFeB permanent magnet additives used in this magnet to add about 2 to 3% of dysprosium can increase its coercivity, the past demand for dysprosium is not, but with the NdFeB Magnet demand increases, it becomes necessary to add elements, grade must be 95 ~ 99.9%, demand is also increasing rapidly. Dysprosium oxide is also used for the preparation of metal dysprosium raw materials, glass, NdFeB permanent magnet additives, but also for metal halide lamp, magneto-optical memory material, yttrium iron or yttrium aluminum garnet, atomic energy industry.
