Hafnium is a silvery gray metal, Melting point: 2506 (or 2233) oC, Boiling point: 4876 [or 4603 °C, Density: 13.31g/cm3, tetravalent transition metal, hafnium chemically resembles zirconium and is found in zirconium minerals. Hafnium is used in filaments and electrodes, Some superalloys used for special applications contain hafnium in combination with niobium, titanium, or tungsten. 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.

Applications: Nuclear reactors, Alloys, Microprocessors,

Most of the hafnium produced is used in the production of control rods for nuclear reactors.

Nuclear reactors: The nuclei of several hafnium isotopes can each absorb multiple neutrons. This makes hafnium a good material for use in the control rods for nuclear reactors. Its neutron-capture cross-section is about 600 times that of zirconium. (Other elements that are good neutron-absorbers for control rods are cadmium and boron.) Excellent mechanical properties and exceptional corrosion-resistance properties allow its use in the harsh environment of a pressurized water reactors

Hafnium is used in iron, titanium, niobium, tantalum, and other metal alloys. An alloy used for liquid rocket thruster nozzles, for example the main engine of the Apollo Lunar Modules is C103, which consists of 89% niobium, 10% hafnium and 1% titanium.

Small additions of hafnium increase the adherence of protective oxide scales on nickel-based alloys. It improves thereby the corrosion resistance especially under cyclic temperature conditions that tend to break oxide scales by inducing thermal stresses between the bulk material and the oxide layer

The electronics industry discovered that hafnium-based compound can be employed in gate insulators in the 45 nm generation of integrated circuits from Intel, IBM and others. Hafnium oxide-based compounds are practical high-k dielectrics, allowing reduction of the gate leakage current which improves performance at such scales.

Other uses: Due to its heat resistance and its affinity to oxygen and nitrogen, hafnium is a good scavenger for oxygen and nitrogen in gas-filled and incandescent lamps. Hafnium is also used as the electrode in plasma cutting because of its ability to shed electrons into air.
