Coster is known as the co-discoverer of Hafnium (Hf) in 1923, along with George Charles Von Hevesy.
Hafnium was discovered by Dirk Coster and Georg von Hevesy in 1923 in Copenhagen, Denmark
Hafnium was discovered in 1923 by Dirk Coster and George Charles von Hevesey. Niels Bohr however was the first scientist who predicted its existence. Hope that helps!
Dirk Coster was born in 1889.
Hafnium was discovered by Dirk Coster and Von Hevesy in zirconium minerals after X-ray spectrometric analysis.
Hafnium is a natural chemical element; hafnium hasn't minerals but it is associated with zirconium (unrefined zirconium contain approx. 2 % hafnium).
Wikipedia :Hafnium (pronounced /ˈhæfniəm/, HAF-nee-əm) is a chemical element with the 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. Hafnium was the penultimate stable isotope element to be discovered (rhenium was identified two years later). Hafnium was found by Dirk Coster and Georg von Hevesy in 1923 in Copenhagen, Denmark, and named Hafnia after the Latin name for "Copenhagen".
Hafnium is primarily obtained as a by-product of zirconium production. It is found in most zirconium minerals, and it is extracted by various chemical processes like solvent extraction or ion exchange. Hafnium is a relatively rare element in the Earth's crust.
Marc de Coster died on July 24, 2012, in Manhattan, New York, USA of cancer.
The element hafnium takes its name from the Latin name for "Copenhagen", which is Hafnia. The discoverers of this element (which had been predicted by the great Mendeleev himself) were Dirk Coster and Georg von Hevesy. They did their work in Copenhagen, which also turns out to be the home town of the Nobel Laureate (physics) Niels Bohr.
Hafnium was discovered by Dirk Coster and György Karl von Hevesy in 1922, in Copenhagen (Denmark), analyzing by X-ray spectrometry minerals containing zircon.
Dirk Harvey was born on February 27, 1923, in Illinois, USA.
Because Dirk Hartog was Dutch, the western half of the Australian continent was called "New Holland".
