4 Uses
4.1 Uses & Benefits
- Currently known uses of Einsteinium metal are limited to research purpose only.
- 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.
