Interesting Facts
- Neodymium is not found free in nature, hence it is not a native metal.
- Neodymium metal found in minerals like Monazite and Bastnaesite.
- Beryllium is best anti corrosion metal.
- Beryllium is the lightest metal and still it is stronger than steel.
- It also finds various applications in Nuclear reactors as a reflector.
