Discovery

In 1789, the M.H. Klaproth (Germany, Berlin university) found that, in 1824, by J.J. Berzelius (Stockholm, Sweden) separate out for the first time.

Source

Exist in zircon (zircon) and inclined zircon (baddeleyite).

Element USES

Zirconium alloys don't absorb neutrons, used in the nuclear field, oblique zircon used in laboratory crucible.
