Zirconium, also known as Zr on the Periodic Table, was first discovered as an element by Martin Heinrich Klaproth in 1789, in Berlin, in a sample of zircon (zirconium silicate) from Sri Lanka. He called the new oxide ‘Zirconerde.’ Although Sir Humphrey Davy was the first to attempt to, Jons J. Berzelius was the first to isolate the metal in 1824, in Stockholm, Sweden. He produced zirconium as an amorphous black powder. The element name comes from the Persian word ‘zargun’ meaning gold-like.
