Abstract
ABSTRACT In this paper, xPb(Mn1/3Sb2/3)O3-(1−x)Pb(Zr0.52Ti0.48)O3 (PMS-PZT) ceramics were fabricated by using conventional ceramics technique. Temperature and frequency dependence of the dielectric properties of ceramics were investigated. For PMS-PZT ceramics with 0.08 ≤ x ≤ 0.15, the maximum dielectric constant decrease as the measurement frequency increases and its permittivity maximum temperature (T m) is shifted towards higher temperatures as well, these behavior show ‘relaxor-like’ ferroelectric behavior. While for x = 0.05, there is no shift in transition temperature which shows normal ferroelectric behavior. The mechanism of dielectric relaxor behavior for high PMS content is discussed in the paper.
