Description
Silvery rare earth metal.
Uses
It is used in the electronics and ceramics industries. It is easily magnetized and very difficult to demagnetize. This suggests important future applications in solid-state and superconductor technologies.
Sources
Found with other rare earths in monazite sand. The sand is often 50% rare earths by weight and 2.8% samarium.
