Zirconium was discovered in 1789 by M.H.Klaproth at the University of Berlin, Germany. First isolated 1824 by J.J. Berzeluis at Stockholm, Sweden.
[Arabic: zargun = gold colour]

Description: Zirconium is a hard, lustrous, silvery metal which is very resistant towards corrosion due to an oxid layer on the surface. However, it will burn in air if ignited. Zirconium is unaffected by acids (exept HF) and alkalis. It is used in alloys, coloured glazes, and nuclear reactors. Its oxides are used in foundry crucibles, bricks, ceramics and abrasives.
