The Discovery of Zirconium - Refractory Metals and Alloys

Mar 21, 2018· He named this new oxide zirconium oxide, and this new element zirconium. Martin was unable to extract pure zirconium since it is similar to hafnium in chemical properties; also, zirconium and hafnium are co-existence in zirconium ore. Until 35 years later, in 1824, the Swedish chemist Berzelius extracted pure zirconium for the first time.

WebElements Periodic Table » Hafnium » historical information

Hafnium was thought to be present in various zirconium minerals many years prior to its discovery, in 1923, which was credited to Dirk Coster and George Charles von Hevesey. It was finally identified in zircon (a zirconium ore) from Norway, by means of X-ray spectroscopic analysis. It was named in honour of the city in which the discovery was made.
