Changes in the electrical conductivity of PbZrO3 in the temperature range 200 to 270 °C are investigated using gold, silver and platinum electrodes. Within this temperature range it is found that a spontaneous current exists in the sample showing changes with temperature analogous to the changes governing the electric conductivity. Study of absorption currents when the polarization field is switched off, reveals current hysteresis loops reminescent of electrical hysteresis loops in ferroelectric materials. Hence, the results obtained indicate the presence of a ferroelectric phase in PbZrO3 as well as an electronic mechanism of conductivity.
