Dysprosium
Name: dysprosium
English: Dysprosium Oxide
Molecular formula: Dy2O3
Molecular Weight: 373.02
CAS: 1308-87-8
Packaging: 10,25,50 kg / bag, inside two plastic bags, outer braid, drum, drum or plastic barrels.
Characters:
White or light yellow powder, density 7.81g / cm3, melting point 2340 ℃, boiling point of about 4000 ℃, for ionic compounds, dissolved with acid and ethanol, but insoluble inalkali, is not soluble in water.Application areas:
NdFeB permanent magnets used as an additive, in which the magnet dysprosium add about 2 to 3 percent, can increase its coercive force, not the past dysprosium demand, but with thedemand for NdFeB magnets increases, it becomes necessary to add elements, grade 95 to beabout 99.9%; used as a phosphor activator, trivalent dysprosium is a promising one-color light-emitting luminescent center material of active ionic species, it is mainly composed of two emission band composed of a yellow light emission, and the other for the blue light-emitting luminescent material doped with dysprosium as phosphor powder. The necessary raw materials for the preparation of large magnetostrictive metal terbium and dysprosium ironalloy (Terfenol) alloy precision mechanical movement can make some activities to berealized; for the determination of the atomic energy industry neutron spectrum or doneutron absorber; also can be used as magnetic refrigeration work with magnetic substances.
