Hafnium Pieces

Hafnium is a silvery colored, ductile metal that is found in all minerals containing zirconium. Hafnium is fabricated into ingot form through vacuum arc melting of material into slab form and then rolling into plate and sheet product. Hafnium can be used to control the recrystallization of tungsten filaments, but its main application is as control rod material in nuclear reactors due to its ability to absorb neutrons. 

1. As hafnium has a remarkable ability to shed electrons into the air and has a high melting point, it is the crucial component of the plasma cutting electrode.

2. Hafnium also has a strong ability to capture neutrons, making it an excellent material for control rods in nuclear reactors.
