zirconium
Element forty, periodic
Zirconium is a metallic element used primarily in nuclear reactors, where its low absorption of neutrons makes it ideal for fuel rod cladding.
The metal resists corrosion and withstands high temperatures.
Zirconium compounds appear in ceramics, abrasives, and some antiperspirants.
The gemstone cubic zirconia is a zirconium oxide crystal.
