• Application: There are not many uses for dysprosium. Scientists continue to experiment with it as apossible alloy metal (it has a high melting point) to be mixed with steel to make control rodsthat absorb neutrons in nuclear reactors. There are only a few commercial uses for dysprosium,such as a laser material and as a fluorescence activator for the phosphors used to produce thecolors in the older TV and computer cathode ray tubes (CRTs). When combined with steelor nickel as an alloy, it makes strong magnets.

Case Study

Dysprosium Used to Enhance the Coercivity of Nd-Fe-B Magnets

Rahimi, Hamed, et al. Journal of Magnetism and Magnetic Materials, 2017, 424, 199-206.

Dysprosium (Dy) is an element with a large magnetocrystalline anisotropy field. Manufacturing Nd-Fe-B magnets with high coercivity is one of the potential ways to synthesize high-performance permanent magnets. The coercive force of Nd-Fe-B magnets is controlled by the microstructure. Adding dysprosium (Dy) to the area near the grain boundary is an effective method to increase the coercive force.
Synthesis procedure of dysprosium-modified Nd-Fe-B magnets
· First, Nd2Fe14B nanoparticles were synthesized via the sol-gel method.
· The (Nd1-xDyx)2Fe14B nanoparticles with different amounts of Dy were prepared by mixing synthesized Nd2Fe14B powders with different weight percentage of Dy powders (purity 99.9%, 200 mesh) using a mill. Hardened steel containers including steel balls and powders were applied in the mechanical alloying process.
· The as-milled powder was then heat treated under vacuum (10-5 Pa) at 800 °C for 60 min.
