Uses & Benefits
- As this metal does not absorb neutrons; It is used in nuclear power stations.
- Its oxide is used in ultra strong ceramics. It is also used in manufacturing Crucibles.
- Dysprosium metal is highly reactive due to which it pure form is not as usual as its alloy.
-
Thi metals alloy is used in magnate as it is resistance to high temperature.
