Description
Summary:In this paper the authors analyse the merits of the impedance spectroscopy technique for studying the sintering process of yttria stabilized zirconia. The great advantage of this technique with respect to classical ones is the possibility of separating the behavior of the grains from grain boundaries during thermal cycles. Because of large conductivities at high temperatures, measurements must be performed in the range 300–600°C after a rapid cooling of the sample down from firing temperature. In this temperature range both intragrain and grain boundary contributions are observable. The results give valuable informations on:•-the solid state reaction of the dopant dissolution into the ZrO2 matrix at the initial stage of the process•-the grain boundary formation and evolution for different firing conditions.
