Abstract
In this work, the results of investigations of the PZT ceramics, received on the base of two - component solid solutions Pb(Zr $_{\rm x}$ Ti $_{1 -{\rm x}})$ O₃ are presented. The samples were obtained by conventional ceramic sintering method with nanopowders received in the sol-gel method. The temperature dependencies of the electric conductivity $\sigma {\rm g}$ or all samples, with different content Zr/Ti ( $0.35 \le x \le 0.65$ ), in the range temperatures of $300 \div 750$ K, were performed. On the base of the ln $\sigma$ T = f(1/T) dependencies, the activation energy E_a was calculated. The determined values of the E_a were limited in the range $0.53 \div 0.71$ eV for ferroelectric phase as well as $0.75 \div 0.80$ eV for paraelectric phase.
