2 Facts
2.1 Interesting Facts
  • Cerium is a rare earth metal but still it is not rare at all.
  • It’s non-toxic compound Cerium sulfide has a rich red color and it is used as a pigment.
  • Cerium metal is also used in Flat screen TVs, light bulb, floodlights, etc.
  • Aluminum’s abundance percentage is more as it is found in more than 260 minerals.
  • Pure Aluminum always reacts with oxygen rapidly.
  • It is a good conductor of heat and electricity and used in transmission lines.
