【 摘 要 】

In the present work the effect of porosity ceramics PZT on the dielectric properties was studied. It is shown that the presence of pores leads to decrease of the real part of the dielectric permittivity in the frequency range of 25 Hz-1 MHz also as to non-stability of the dielectric characteristics in the phase transition region.
