Hafnium is element number 72. All the elements at http://www.periodicvideos.com/
"Hafnium" is a chemical element with symbol "Hf" and atomic number 72. A lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in zirconium minerals. Its existence was predicted by Dmitri Mendeleev in 1869, though hafnium was not identified until 1923, making it the penultimate stable isotope element to be discovered . Hafnium is named after "Hafnia", the Latin name for Copenhagen, where it was discovered.
Hafnium is used in filaments and electrodes. Some semiconductor fabrication processes use its oxide for integrated circuits at 45 nm and smaller feature lengths. Some superalloys used for special applications contain hafnium in combination with niobium, titanium, or tungsten.
Hafnium's large neutron capture cross-section makes it a good material for neutron absorption in control rods in nuclear power plants, but at the same time requires that it be removed from the neutron-transparent corrosion-resistant zirconium alloys used in nuclear reactors.
Hafnium is a shiny, silvery, ductile metal that is corrosion-resistant and chemically similar to zirconium . The physical properties of hafnium metal samples are markedly affected by zirconium impurities, especially the nuclear properties, as these two elements are among the most difficult to separate because of their chemical similarity.
A notable physical difference between these metals is their density, with zirconium having about one-half the density of hafnium. The most notable nuclear properties of hafnium are its high thermal neutron-capture cross-section and that the nuclei of several different hafnium isotopes readily absorb two or more neutrons apiece. In contrast with this, zirconium is practically transparent to thermal neutrons, and it is commonly used for the metal components of nuclear reactors – especially the claddings of their nuclear fuel rods.

Name Origin
From Hafnia, the Latin name of Copenhagen.
"Hafnium" in different languages.
Sources
Hafnium does not exist in nature in elemental form. Obtained from the minerals alvite ([(Hf, Th, Zr)SiO4.H2O]), thortveitite ((Sc,Y)2Si2O7) and zircon (ZrSiO4 which usually contain between 1 and 5% hafnium.
Uses
Used in gas-filled and incandescent lamps, reactor control rods because of its ability to absorb neutrons also as a gas scavenger in vacuum tubes. Used as the electrode in plasma cutting because of its ability to shed electrons into air.
It is also used in iron, titanium, niobium, tantalum and other metal alloys.

The Dutch physicist Dirk Coster and the Hungarian chemist George de Hevesy may not have had an eye for the little mermaid when they discovered hafnium through X-ray spectroscopy of Norwegian zircon in Copenhagen in 1923. What they found here was an element which is now regarded as a specialist for very special tasks. The new raw material got its name from „Hafnia", the Latin name of Copenhagen. Hafnium is difficult to extract - it must be first isolated with difficulty from zirconium in order to get to the coveted raw material. This is not possible during the manufacturing process, but takes place in a separate process. It comes mostly from Australia and South America - the steel-grey metal of high density; the estimated global presence is around one million tonnes. Resources, which are very much required: Steel is now mostly cut using a plasma torch that does not require any hazardous gas, but only air and electricity. A small head made of pure hafnium is included in its copper electrode. The metal is not only extremely corrosion-proof and has a high melting point, but also another property that makes it unique: The ability to discharge electrons in the air. For this, even a small amount of energy is enough for hafnium, which is why the electrode head with hafnium works at a cooler temperature and the plasma torch burns hotter at the same time. Another key application is the nuclear technology, where hafnium is used in nuclear reactors, as well as the use in computer chips that would not achieve by far their present performance without the rare element. „This is one of the major changes in the last 40 years," said David Perlmutter, Senior Vice President and General Manager of the Mobility Group of the chip manufacturer, Intel. The production using hafnium instead of the mostly used silicon promises less leakage currents, more speed and lower production costs. For more information, visit: www.swissmetal.net

Hafnium MCV The Safety Challenges of Nuclear Waste Containment
The Safety Challenges of Nuclear Energy Nuclear energy plays a key role by providing 13% of the world's energy, but is one of the more controversial energy sources out there. Although the carbon footprint of nuclear energy is virtually zero, the political and safety risks associated with it cause people to have strong opinions on whether or not it should be used. A major part of the materials challenge of nuclear energy is improving safety through focusing on material degradation issues. Because the materials in nuclear power plants are exposed to extreme conditions, corrosion and cracking of structural parts is a large safety problem. Austentic stainless steels are the primary structural material used, while nickel-based alloys are used for higher-strength needs such as springs, tub... -

"Hafnium" is a chemical element with symbol "Hf" and atomic number 72. A lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in zirconium minerals. Its existence was predicted by Dmitri Mendeleev in 1869, though hafnium was not identified until 1923, making it the penultimate stable isotope element to be discovered . Hafnium is named after "Hafnia", the Latin name for Copenhagen, where it was discovered.
Hafnium is used in filaments and electrodes. Some semiconductor fabrication processes use its oxide for integrated circuits at 45 nm and smaller feature lengths. Some superalloys used for special applications contain hafnium in combination with niobium, titanium, or tungsten.
Hafnium's large neutron capture cross-section makes it a good material for neutron absorption in control rods in nuclear power plants, but at the same time requires that it be removed from the neutron-transparent corrosion-resistant zirconium alloys used in nuclear reactors.
Hafnium is a shiny, silvery, ductile metal that is corrosion-resistant and chemically similar to zirconium . The physical properties of hafnium metal samples are markedly affected by zirconium impurities, especially the nuclear properties, as these two elements are among the most difficult to separate because of their chemical similarity.
A notable physical difference between these metals is their density, with zirconium having about one-half the density of hafnium. The most notable nuclear properties of hafnium are its high thermal neutron-capture cross-section and that the nuclei of several different hafnium isotopes readily absorb two or more neutrons apiece. In contrast with this, zirconium is practically transparent to thermal neutrons, and it is commonly used for the metal components of nuclear reactors – especially the claddings of their nuclear fuel rods.

A lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in zirconium minerals. Its existence was predicted by Dmitri Mendeleev in 1869, though hafnium was not identified until 1923, making it the penultimate stable isotope element to be discovered . Hafnium is named after "Hafnia", the Latin name for Copenhagen, where it was discovered.
Hafnium is used in filaments and electrodes. Some semiconductor fabrication processes use its oxide for integrated circuits at 45 nm and smaller feature lengths. Some superalloys used for special applications contain hafnium in combination with niobium, titanium, or tungsten.
Hafnium's large neutron capture cross-section makes it a good material for neutron absorption in control rods in nuclear power plants, but at the same time requires that it be removed from the neutron-transparent corrosion-resistant zirconium alloys used in nuclear reactors.
Hafnium is a shiny, silvery, ductile metal that is corrosion-resistant and chemically similar to zirconium . The physical properties of hafnium metal samples are markedly affected by zirconium impurities, especially the nuclear properties, as these two elements are among the most difficult to separate because of their chemical similarity.
A notable physical difference between these metals is their density, with zirconium having about one-half the density of hafnium. The most notable nuclear properties of hafnium are its high thermal neutron-capture cross-section and that the nuclei of several different hafnium isotopes readily absorb two or more neutrons apiece. In contrast with this, zirconium is practically transparent to thermal neutrons, and it is commonly used for the metal components of nuclear reactors – especially the claddings of their nuclear fuel rods.

Name Origin
From Hafnia, the Latin name of Copenhagen.
"Hafnium" in different languages.
Sources
Hafnium does not exist in nature in elemental form. Obtained from the minerals alvite ([(Hf, Th, Zr)SiO4.H2O]), thortveitite ((Sc,Y)2Si2O7) and zircon (ZrSiO4 which usually contain between 1 and 5% hafnium.
Uses
Used in gas-filled and incandescent lamps, reactor control rods because of its ability to absorb neutrons also as a gas scavenger in vacuum tubes. Used as the electrode in plasma cutting because of its ability to shed electrons into air.
It is also used in iron, titanium, niobium, tantalum and other metal alloys.

The Dutch physicist Dirk Coster and the Hungarian chemist George de Hevesy may not have had an eye for the little mermaid when they discovered hafnium through X-ray spectroscopy of Norwegian zircon in Copenhagen in 1923. What they found here was an element which is now regarded as a specialist for very special tasks.
The new raw material got its name from „Hafnia", the Latin name of Copenhagen. Hafnium is difficult to extract - it must be first isolated with difficulty from zirconium in order to get to the coveted raw material. This is not possible during the manufacturing process, but takes place in a separate process. It comes mostly from Australia and South America - the steel-grey metal of high density; the estimated global presence is around one million tonnes. Resources, which are very much required: Steel is now mostly cut using a plasma torch that does not require any hazardous gas, but only air and electricity. A small head made of pure hafnium is included in its copper electrode. The metal is not only extremely corrosion-proof and has a high melting point, but also another property that makes it unique: The ability to discharge electrons in the air. For this, even a small amount of energy is enough for hafnium, which is why the electrode head with hafnium works at a cooler temperature and the plasma torch burns hotter at the same time. Another key application is the nuclear technology, where hafnium is used in nuclear reactors, as well as the use in computer chips that would not achieve by far their present performance without the rare element. „This is one of the major changes in the last 40 years," said David Perlmutter, Senior Vice President and General Manager of the Mobility Group of the chip manufacturer, Intel. The production using hafnium instead of the mostly used silicon promises less leakage currents, more speed and lower production costs.

The Safety Challenges of Nuclear Energy
Nuclear energy plays a key role by providing 13% of the world's energy, but is one of the more controversial energy sources out there. Although the carbon footprint of nuclear energy is virtually zero, the political and safety risks associated with it cause people to have strong opinions on whether or not it should be used. A major part of the materials challenge of nuclear energy is improving safety through focusing on material degradation issues. Because the materials in nuclear power plants are exposed to extreme conditions, corrosion and cracking of structural parts is a large safety problem. Austentic stainless steels are the primary structural material used, while nickel-based alloys are used for higher-strength needs such as springs, tubes, and fasteners. The reason such materials are used is that they have good aqueous corrosion resistance at high temperatures. Finding alloys that are better suited for such conditions and alloys that are suited to the specific conditions in the new generation of power plants being created seems to be an important piece of improving the safety of nuclear power.
Not only is it important for materials to be noncorrosive and capable of withstanding high pressures and temperatures, but they must also have low friction and be radiation insulating. To ensure resistance to high pressures the grain boundaries are carefully planned in the metal, and metals with strong intermolecular forces are used to keep them from breaking. Any friction can create air cavities, cause the wearing away of the pipes and decrease the flow rate through the system. All of this leads to less profitability, as pipes must be changed more frequently and a less efficient transfer of energy
With some power plants having several decades of operation, even the best materials develop irregularities and require part replacements from time to time. To determine which pipes are at risk of bursting or developing cracks, 'eddy current testing' is performed, whereby an electromagnetic force is measured through the pipe and any irregularities in the lattice structure are detected by a weakening of the magnetic force. The lifetime of a nuclear power plant comes down to how long its materials will last and so materials improvements will provide economic benefits in addition to safety ones.
