Zirkonium - Wikipedia

Ontdekking. Zirkonium is in 1789 ontdekt door de Duitse scheikundige Martin Heinrich Klaproth tijdens het onderzoeken van een jargon, een lichte zirkoon, uit Sri Lanka.Hij noemde het nieuwe element Zirkonerde (zirconia). In 1824 is het in onzuivere vorm voor het eerst geïsoleerd door de Zweedse chemicus Jöns Jacob Berzelius door een mengsel van kalium en zirkoniumfluoride te verhitten.
