Abstract

In ceramic materials, depolarization effects take place when an external electrical field is removed. Therefore, an understanding of mechanisms of polarization and depolarization is important for a more accurate control of furnace temperature and DC or pulse electrical field in flash sintering. In this paper, depolarization currents were measured in illitic clay samples in the temperature range 450–1100 °C for 150–300 min. The ionic component was dominant in these depolarization currents. Time dependences of depolarization currents suggested several depolarization mechanisms took place. They were caused by localized hopping or migration of K+, Na+, H+, and OH− ions, which were the dominant charge carriers in various temperature ranges, in the internal electric field induced by space charges at electrodes. Depolarization is a long-lasting process at high temperatures and influences the internal electrical field in ceramics.
