Abstract

A few GPa-order high-pressure impedance measurement was performed by utilizing an indentation method, which is often used to evaluate mechanical characteristics, and the alternating current (AC) impedance method simultaneously. We succeeded in estimating the activation volume (ΔV = 3.2 cm3/mol) for O2− ion conduction of YSZ with a single sweep of load at 0.25 N/s up to 25 N. Such a quick and easy method for determining ΔV is completely new that has not been proposed so far.
