“…It has been suggested that the increase in 90 • domain wall reorientation by poling reduces k p and enhances anisotropy [10]. Also strong clamping caused by 90 • domain reorientation is attributed to vanishing of k p [40].…”

“…5. 8 The mixture rule depends on composition, crystal structure, degrees of crystallization, polarization, and morphology, which includes grain size, grain boundary, and pore size of lead zirconate particles. The G 0 temporal characteristics of the samples were recorded in the linear viscoelastic regime at electrical¯eld strengths of 1 and 2 kV/mm, and at the frequency of 1 rad/s.…”

Perovskite lead zirconate (PbZrO 3 Þ was synthesized in an orthorhombic form at a temperature below the Curie temperature, T C . The orthorhombic form is a noncentrosymmetric structure which is capable of spontaneous polarization. Fourier transform infrared (FTIR) spectra and X-ray di®raction (XRD) patterns con¯rm the successful synthesis of the lead zirconate; and scanning electron microscopy (SEM) micrographs indicate that PbZrO 3 particles are moderately dispersed in the natural rubber (NR) matrix. Without an electrical¯eld, the particles merely act as a ferroelectric¯ller, which can absorb and store additional stress. Under an electrical¯eld, particle-induced dipole moments are generated, leading to interparticle interaction and a substantial increase in the storage modulus. At a small amount of lead zirconate particulates present in the natural rubber matrix, at a volume fraction of 0.007306, the electrical conductivity increases dramatically by nearly two orders of magnitude at the electrical frequency of 500 kHz.

“…With the substitution of some lead ions by calcium ions, it is possible to reduce the tetragonality, i.e., the (c/a) ratio, which decreases the coercive field [2,3]. The substitution of titanium ions by manganese ions reduces the conductivity [4].…”

Abstract. Powders of (Pb0.8Cao.2)(Wi0.99Mno.o 1)O3 have been prepared by sol-gel processing. A tetragonal phase is formed after heat treatment at as low as 800~ The tetragonality was found to be 1.053 q-0.005 and Curie temperature 315~ Composite films with 0-3 connectivity were prepared from 800~ heat treated powders and P(VDF-TrFE) by the solvent casting technique. Composites poled at 20 MV/m, exhibited a pyroelectric coefficient of 17.4/zC/m2K and a pyroelectric figure of merit (FOMp = p/e) of 0.51/zC/m2K.
