Material Notes:

Zirconium resists corrosive attack in most organic and mineral acids, strong alkalis, and some molten salts. A tightly adherent and protective oxide film protects the metal-oxide interface to provide corrosion resistance. An additional benefit for zirconium alloys in long-term geological disposal options is the inert nature of zirconium oxide.Information provided by ATI Wah Chang
