Description

General description

Zirconium(IV) oxynitrate hydrate is a crystalline zirconium compound that exhibits high solubility in water. It typically comprises amixture of oxide and a slightly hydroxide form.

Application

Zirconium(IV) oxynitrate hydrate is used to prepare CeO₂-ZrO₂ mixed oxide catalyst supports. It may be used as zirconium precursor in the preparation of;

• Pb(Zr_0.50Ti_0.50)O₃ ferroelectric thin films,
• silica- and alumina-doped nanocrystalline ceria/zirconia (Ce_0.5Zr_0.5O₂).
