Product details
The mainly use of dysprosium is:
(1) Addition agent use as the indisputable boron system permanent magnet of neodymium being added the dysprosium of 2~3%'s left and right sides in this kind of magnetic body, and can raise its coercive force, and the requirement capacity of dysprosium was not very in the past, but the increase along with the indisputable boron magnetic body requirement of neodymium, it becomes the necessary element adding, and the grade must be about 95 - 99.9%.
(2) The dysprosium is used as the phosphor powder activator, and the three prices dysprosiums are one kind of activation ions of single shot that has future light center three primary colourss luminescent materials, and its two of major cause is launched taking forming, and one for the yellow light emission, and another is for the blue light emission, and the luminescent material to mix the dysprosium can be regarded three primary colours phosphor powder.
(3) Dysprosium is the metal raw material to prepare big magnetostrictive alloy terbium dysprosium iron necessity of ( Terfenol ) alloy, and can make some precisely activities of mechanical movement realized.
(4) The available magnetism light done of dysprosium metal stores the material, and possesses higher record speed and the read number susceptibbility.
(5) Being used to make dysprosium lamp, the work matter which in adopted the dysprosium in the lamp is the iodization dysprosium, and this kind of lamps and lanterns have the merits such as brightness is big and the colour good and colour temperature height and volume are small and stable arc etc, and have been used illumination light sources such as film and printing etc.
(6) Owing to the dysprosium element possess the big specific property of neutron capture sectional area, and in is used for ascertaining by measuring or surveying the neutron energy spectrum or doing the neutron absorption pharmaceutical preparation the atomic energy in the industry.
(7) Dy3Al5O12 still can be used as the magnetism refrigeration with the magnetism work matter.
