ስለ 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.

ፕሮግራሞች

Neodymium magnets (thermal stability additive), nuclear reactor control rods, and data storage.

ሐቅ

Dysprosium's name literally means 'hard to get' in Greek, reflecting how difficult it is to separate from other rare earths.
