What is Hafnium? Hafnium was discovered in 1923 by Dirk Coster and George Charles von Hevesey. Hafnium is a shiny and silvery metal exhibiting ductile features. Hafnium became the second-to-last element with stable isotopes to be discovered, when it was found by Dirk Coster and Georg von Hevesy in 1923 in Copenhagen, Denmark, who originally named it Hafnia after the Latin name of "Copenhagen". Hope that helps! Hafnium in heat-resistant alloys is used as an additive element, such as tungsten, molybdenum and Tantalum Alloys, adding hafnium. Physical Properties of HfC can be used as an additive for cemented carbide due to its high hardness and high melting point. In 1923 he also discovered, with the Dutch physicist Dirk Coster, the element hafnium. Originally there was significant controversy over who had actually discovered hafnium as the chemist Georges Urbain used a chemical technique with rare earth elements to produce a substance that he called celtium. Hope that helps! His development of isotopic tracer techniques greatly advanced understanding of the chemical nature of life processes.
Anton Eduard van Arkel and Jan Hendrik de Boer discovered a method for producing high purity hafnium in 1925. Hafnium was almost the last non-radioactive element to be discovered (rhenium was the last). Niels Bohr however was the first scientist who predicted its existence. Hafnium (Hf), chemical element (atomic number 72), metal of Group 4 (IVb) of the periodic table.It is a ductile metal with a brilliant silvery lustre.The Dutch physicist Dirk Coster and the Hungarian Swedish chemist George Charles von Hevesy discovered (1923) hafnium in Norwegian and Greenland zircons by analyzing their X-ray spectra. Who Discovered Hafnium. The men took the element's name from Hafnia , the Latin word for Copenhagen , the city where it was discovered and the capital of Denmark. A lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in zirconium minerals. Originally there was significant controversy over who had actually discovered hafnium as the chemist Georges Urbain used a chemical technique with rare earth elements to produce a substance that he called celtium. Hafnium is a tetravalent transition metal with atomic number 72 and represented with the symbol Hf in the Periodic Table. Hafnium, Latin for “Copenhagen,” was discovered in Copenhagen, Denmark in 1924. Niels Bohr however was the first scientist who predicted its existence. Hafnium (Hf), chemical element (atomic number 72), metal of Group 4 (IVb) of the periodic table.It is a ductile metal with a brilliant silvery lustre.The Dutch physicist Dirk Coster and the Hungarian Swedish chemist George Charles von Hevesy discovered (1923) hafnium in Norwegian and Greenland zircons by analyzing their X-ray spectra. Its atomic number is 40 and its chemical symbol is Zr.

Hafnium was discovered in 1923 as a novel metal by Hevesy and Coster. Hafnium can be used as a getter for many inflatable systems. Hf was named after the city in which it was discovered in, Copenhagen whose Latin name is Hafnia. Hevesy teamed with Danish chemist Dirk Coster, and the two discovered hafnium in 1923. Georg von Hevesy and Dutch physicist Dirk Coster discovered hafnium in 1923 using x-ray spectroscopy to analyze zirconium ores. In 1913, the physicist Henry Moseley, working in Manchester and later Oxford, discovered an experimental method for ordering the elements according to their atomic numbers. Hf was named after the city in which it was discovered in, Copenhagen whose Latin name is Hafnia.
