Hafnium

Hafnium (Hf)

Hafnium is the 72nd element in the periodic table and has a symbol of Hf and atomic number of 72. It has an atomic weight of 178.49 and a mass number of 180. Hafnium has seventy-two protons and one hundred eight neutrons in its nucleus, and seventy-two electrons in six shells. It is located in group four, period six and block d of the periodic table. Silvery lustrous metallic transition element. Used in tungsten alloys in filaments and electrodes, also acts as a neutron absorber. First reported by Urbain in 1911, existence was finally established in 1923 by D. Coster, G.C. de Hevesy in 1923.

History

In 1911, Georges Urbain claimed to have found the element in rare-earth residues which was shown later to be a mixture of already discovered lanthanides. Dirk Coster and George de Hevesy found it by X-ray spectroscopic analysis in Norwegian zircon in 1922. Anton Eduard van Arkel and Jan Hendrik de Boer were the first to prepare metallic hafnium by passing hafnium tetra-iodide vapor over a heated tungsten filament in 1924. From Hafinia, the Latin name for Copenhagen

DiscoverersDirk Coster, Georg von Hevesy
Discovery LocationDenmark
Discovery Year1923
Etymology (Name Origin)From Hafnia, the Latin name of Copenhagen.
PronunciationHAF-ni-em (English)
Hafnium is considered to be non-toxic
In powdered form, hafnium is pyrophoric and can ignite spontaneously in air

Uses

Hafnium oxide-based compounds are being introduced into silicon-based chips to produce smaller, more energy efficient and performance packed processors. Most of the hafnium produced is used in the production of control rods for nuclear reactors. Hafnium is also used in photographic flash bulbs, light bulb filaments, and in electronic equipment as cathodes and capacitors. Used in reactor control rods because of its ability to absorb neutrons.

Sources

Obtained from mineral zircon or baddeleyite.
