Perovskite solid solution (1-x)Pb(Zr0.52Ti0.48)O3-xY(Ta1/2Sb1/2)O3 ceramics
(abbreviated as PZT-YTS, where x = 0, 0.01, 0.02, 0.03, 0.04 and 0.05) were
synthesized by conventional solid state method. The phase structure,
microstructure and corresponding electrical properties were studied. X-ray
diffraction and Raman analyses show that tetragonal phase structure was
obtained in all ceramics at room temperature. Scanning electron micrographs
of the samples show uniform grain distribution and grain growth inhibition
with the increase of doping content. The dielectric permittivity,
dissipation factor, electromechanical coupling factor, Young modulus,
mechanical quality factor, piezoelectric charge constant, actual density and
piezoelectric voltage constant, for the ceramics with x = 0.04 were: ?r =
714.9, tan ? = 0.03345, KP = 0.635, Y = 10.528 ? 1010 N/m2, Qm = 622.254,
d31 = 74.738 ? 10?12 C/N, ?a = 7.67 g/cm3 and g31 = 10.477 ? 10?3 m?V/N,
respectively, which are optimal in comparison to other studied samples.
