The Conductivity of self-made ZrO2-9mol%Y2O3 electrolyte film is measured at high temperature by four-electrodes method and its ionic conductive properties is studied. The results show that the conductivity of ZrO2 film is one order of magnitude greater than bulk ZrO2 at high temperature. The relationship between conductivity and temperature satisfies the Arrhenius equation. The requirement is reached that ionic transport number greater than 0.99.(5 refs.)
