Hafnium - Grayish Metallic Solid Powder, Cas No. 7440-58-6, Atomic Number 72, Atomic Weight 178.49 G/mol, High Density 13.31 G/cm³, Excellent Neutron Absorption

Hafnium is most widely used in nuclear power plants. One of the best physical properties of hafnium is that it reacts very well with neutrons (small particle in the nucleus of an atom). Hence, hafnium is used in nuclear fission reactors where two atoms are collided against each other in a controlled process. When the atoms break, a huge amount of nuclear energy is released, which is then converted into electricity. Hafnium has the capacity to absorb a lot of neutrons. This is why it is used in making rods to control nuclear fission reactions. This is one of the most important uses of hafnium.
Hafnium is also used to make binary compounds, which are very good refractory materials. Refractory materials have the capacity to endure high temperatures. This makes them perfect for lining furnaces and refractory ovens.
