Quantifiable models for surface protonic conductivity in porous oxides – case of monoclinic ZrO2

The surface protonic conductivity of porous monoclinic ZrO2 sintered at temperatures in the range 700–1100 °C yielding relative densities of around 60% and grain sizes of approximately 160 nm has been studied using impedance spectroscopy as a function of temperature well below the sintering temperat...
