Zirconium Information

Grey-white metallic transition element. Five natural isotopes and six radioactive isotopes are known. Used in nuclear reactors for a Neutron absorber. Discovered in 1789 by Martin Klaproth, isolated in 1824 by Berzelius.

Used in alloys such as zircaloy which is used in nuclear applications since it does not readily absorb neutrons. Also baddeleyite is used in lab crucibles. Used in high-performance pumps and valves. Clear zircon (ZrSiO4) is a popular gemstone.
