Zircadyne.doc Zirconium Corrosion Scribd

Zirconium and its alloys are standard materials for cladding nuclear fuels, since they are corrosion resistant and transparent to thermal neutrons. However, hafnium, zirconium's sister metal, is always present in zirconium ores. Most of zirconium's and hafnium's properties are similar.
