Abstract
In this work, the results of investigations of the PZT ceramics, received on the base of two - component solid solutions Pb(Zr x Ti 1-x )O 3 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 σg or all samples, with different content Zr/Ti (0.35 ≤ x ≤ 0.65), in the range temperatures of 300 ÷ 750K, were performed. On the base of the InaT = 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 ÷ 0.71 eV for ferroelectric phase as well as 0.75 ÷ 0.80 eV for paraelectric phase.
