Impure Zirconium was isolated by Berzelius in 1824. Zirconium occurs in S-type stars, in the Sun and in Moon rocks. The nuclear industry uses Zirconium because it resists the corrosive environments in atomic reactors. It is used to make surgical tools and poison ivy lotions. Zirconium comes from the Arabic word zargun, describing the gemstone zircon.
