Abstract

The dielectric, ferroelectric, and piezoelectric13; properties of ceramic materials of compositions13; (1 x2013; x)[Pb0.91La0.09(Zr0.60Ti0.40)O3]x2013;x[Pb(Mg1/3Nb2/3)O3],13; x = (0, 0.2, 0.4, 0.6, 0.8, and 1.0) were studied. The above13; compositions were prepared by mixing the individual13; Pb0.91La0.09(Zr0.60Ti0.40)O3 (PLZT) and Pb(Mg1/3Nb2/3)13; O3 (PMN) powders in order to design materials with13; different combination of piezo and dielectric properties.13; The powders were calcined at 850 C for 4 h. The presence13; of various phases in the calcined powders was13; characterized by X-ray diffraction (XRD) technique.13; The compacts were prepared by uniaxial pressing and13; were sintered at 1250 C for 2 h. The sintered compacts13; were electroded, poled at 2 kV/mm dc voltage and their13; dielectric, ferroelectric, and piezoelectric properties13; were measured. In general, it was observed that the13; dielectric constant, loss factor and the slimness of the13; ferroelectric curves increase with the PMN content13; while the remnant polarization, saturation polarization,13; and the coercive fields were decreased. It is now possible13; to design materials with a wide combination of d33, K,13; and loss factor by varying PLZT and PMN ratio.
