About Dy

dysprosium

Dysprosium is a chemical element with symbol Dy and atomic number 66. It is a rare earth element with a metallic silver luster.
Dysprosium is used for its high thermal neutron absorption cross-section in making control rods in nuclear reactors, for its high magnetic susceptibility in data storage applications, and as a component of Terfenol-D. Soluble dysprosium salts are mildly toxic, while the insoluble salts are considered non-toxic.
