Hafnium is a lustrous, silvery, ductile metal. It resists corrosion because of the oxide film on its surface, chemically similar to zirconium.
Hafnium is a good absorber of neutrons and is used for nuclear reactor control rods. It also has a high melting point and corrosion resistance, so hafnium can be used in high-temperature alloys and ceramics.
The physical properties of Hafnium are affected by the zirconium impurities. These two elements are contained in zirconium ores at a ratio of about 50 to 1, and zirconium is difficult to separate from zirconium due to their chemical similarity. SAM's Hafnium metal products are all more than 99.50% pure.
-As hafnium has a great ability to shed electrons into the air and has a high melting point, it is the crucial component of the electrode in plasma cutting.
-Hafnium also has a strong ability to capture a neutron, making it a great material for control rods in the nuclear reactors.
-Hafnium is also used as an additive to alloys.
-Hafnium is also used as an additive to alloys. Recently, scientists at Intel and IBM found hafnium-based compounds can be applied in gate insulators to make the processors even smaller.
-Hafnium wires and other Hf parts are also used in plasma cutting because of its ability to shed electrons into the air.
-Be used to control the recrystallization of tungsten filaments.
