| Abstract: | xPb(Zr0.47Ti0.53)O3-(0.925-x)Pb(Zn1/3Nb2/3)O3-0.075Pb(Mn1/3Nb2/3)O3+0.7%wt
Li2CO3 (PZT-PZN-PMnN) ceramics with x=0.65-0.9 have been
prepared by two-stage calcination method. The effect of the PZT content on the
relaxor behavior and ferroelectric properties of ceramics has been
investigated. The degree of diffuseness ( ) from 1.72 to 1.85
indicates that all of compositions show a diffused phase transition with the
strong frequency dispersion, which is characteristic of relaxor ferroelectric
materials. The sharpness of the permittivity peak shows that the compositions
are gradually approached normal ferroelectric behavior when the mol fraction of
PZT increases. At x = 0.80, dielectric and ferroelectric properties of ceramics
are optimal with the mass density ( ) of 7.81
g/cm3, the dielectric constant (εr) of 1230, the dielectric loss (tan ) of 0.005 and the remanent polarization (Pr) of 27 mC/cm2.
