Dielectric characteristics of Pb(Zr0.52-xYxTi0.48)O3 (x = 0.00, 0.10 and Y = Mn/Ce) ferroelectric bulk ceramics.

Lead zirconate titanate (PZT) ceramics of morphotropical phase boundary (MPB) region possess prodigious physical properties such as high relative dielectric constant (ɛr), low relative tangent loss (tan δ), high Curie temperature (Tc), etc. In this work, the ferroelectric ceramics of chemical stoichiometry Pb(Zr0.52-xYxTi0.48)O3, x = 0.00, 0.10 and Y = Mn/Ce (PZ(M/C)T) have been synthesized using solid state synthesis. Results indicated that the PZ(M/C)T compounds exhibit the ferroelectric nature. The Tc values of PZT, PZMT and PZCT compounds are 375.17 °C, 272.25 °C and 373.05 °C respectively. Hence, with the substitution of Mn/Ce ions, the Tc of PZT has been reduced. Further, the loss of PZT has also been reduced due to the substitution of Mn/Ce ions at the zirconium site. Also reported in this paper is the quantitative diffusiveness of the compounds, calculated using Curie-Weiss expression. [ABSTRACT FROM AUTHOR]
