Structure and dielectric properties of electrochemically grown ZrO2 films

The dielectric properties of electrochemically grown zirconium oxide films by anodisation of zirconium in 1.0 mol dm?3 phosphoric acid solution were investigated in a 3 to 30 V potential range with a view to inducing surface modifications for eventual use in biomedical and electronic applications.
