Facts about the
Definition of the Element Hafnium
The Element Hafnium is defined as...
A brilliant, silvery, metallic element separated from ores of
zirconium and used in nuclear reactor control rods, as a getter
for oxygen and nitrogen, and in the manufacture of tungsten
filaments. The most common uses of Hafnium are
in Nuclear reactors, Hafnium reactor, the Hafnium bomb, used in
incandescent lamps and Tungsten filaments
Interesting Facts
about the Origin and Meaning of the element name Hafnium
What are the origins of the word Hafnium ?
The word Hafnium originates from the Latin Hafnia for
"Copenhagen".
Facts about the
Classification of the Element Hafnium
Hafnium is classified as a "Transition Metal" which are located in
Groups 3 - 12 of the Periodic Table. An Element classified as a
Transition Metals is ductile, malleable, and able to conduct
electricity and heat.
Brief Facts about the
Discovery and History of the Element Hafnium
Hafnium was discovered by Dirk Coster and Georg von Hevesy in 1923
in Copenhagen, Denmark. Found in zircon through X-ray spectroscope
analysis in Norway. First separated from zirconium through
re-crystallization of double ammonium or potassium fluorides by
Jantzen and von Hevesey. Metallic Hafnium was first prepared by
Anton Eduard van Arkel and Jan Hendrik deBoer. Associated with
zirconium by using the Bohr theory.

Facts and Info about
the element Argon - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the
International Union of Pure Applied Chemistry, IUPAC, in 1985
which includes the Hafnium element. The famous Russian Scientist,
Dimitri Mendeleev, perceived the correct classification method of
"the periodic table" for the 65 elements which were known in his
time. Hafnium was discovered by Dirk Coster and Georg von Hevesy
in 1923 in Copenhagen, Denmark. Found in zircon through X-ray
spectroscope analysis in Norway. First separated from zirconium
through re-crystallization of double ammonium or potassium
fluorides by Jantzen and von Hevesey. Metallic Hafnium was first
prepared by Anton Eduard van Arkel and Jan Hendrik deBoer. The Standardised Periodic Table now recognises more periods
and elements than Dimitri Mendeleev knew in his day but still all
fitting into his concept of the "Periodic Table" in which
Hafnium is
just one element that can be found.
