5 Uses
5.1 Uses & Benefits
- 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.
- Magnets of Samarium cobalt alloy are stronger than that of Iron and hence, they are used in microwave application.
- Samarium metal also used in optical lasers and infrared absorbing glasses and as a neutron absorber.
