History

• The name Niobium came from the word "Niobe" which
  means "daughter of Tantalus.
• At first, this mineral sample was thought to
  be chromium...

4
The Discovery!

• After experimenting with the mineral it was
  determined that this mineral was not chromium,
  but some oxide of an unknown element. 

• The new element was named columbium.

5
The New Name

• It was later determined that columbium and
  niobium were the same element and some scientist
  tried to change the name niobium back to
  columbium. This idea failed.

6
The Preparation

• The metal Niobium was prepared for the first time
  in 1864 by Blomstrand who reduced the chloride by
  heating it in a hydrogen atmosphere.

This is a virtual representation of niobium metal
in the form of a cup.

• Melting Point- 2468 C
• Boiling Point- 4927 C
• Number of Protons/Electrons- 41
• Number of Neutrons- 52
• Classification- Transition Metal

8
Important Uses

• Along with titanium, Niobium is frequently used
  in pacemakers, artificial joints, and dental
  implants.

• It is used in arc-welding rods for stabilizing
  the different forms of stainless steel.

9
More Uses

• Larger amounts of niobium are used in advanced
  air frame systems.

• Because it does not react with uranium and how it
  does not corrode, Niobium has been used in
  nuclear reactors.

10
Appearences

• Niobium occurs primarily in two minerals,
  columbite and pyrochlore. 
• The abundance of niobium in the Earth's crust is
  estimated to be about 20 ppm. (parts per million)

11
Fun Fact

• Did you know that the most powerful magnet in
  the world is made out of niobium?
• Now you do
