Facts

Interesting Facts
  • Niobium metal was used to get called Columbium in past.
  • Niobium metal found freely in nature (abundance).
  
  • 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.
