About Dysprosium
Dysprosium is a relatively hard, lustrous, silvery rare earth metal with one of the highest magnetic susceptibilities. It is added to neodymium magnets to maintain performance at high temperatures.
Gebruiks & Programme
Neodymium magnets (thermal stability additive), nuclear reactor control rods, and data storage.
Fun Fact
Dysprosium's name literally means 'hard to get' in Greek, reflecting how difficult it is to separate from other rare earths.
