Variations in properties with composition in lead zirconate-titanate ceramics / T.B. Weston, Mineral Processing ; A.H. Webster, Mineral Sciences ; V.M. McNamara, Extraction Metallurgy. : M38-8/52E-PDF
"Lead zirconate-lead titanate ceramics, covering the compositional range 40 to 70 mole per cent lead zirconate, were prepared by cold pressing and sintering from co-precipitated powders. For these ceramics the maxima in the values of dielectric constant and electromechanical coupling factor that occur at the rhombohedral-tetragonal boundary were found to be higher and sharper than previously reported for unmodified lead zirconate-titanate. Dielectric and mechanical losses were lower in the tetragonal than in the rhombohedral phase. Determination of the variations in properties with temperature confirmed the previously reported shift in the phase boundary toward higher zirconate compositions with increasing temperature. It was found that changes in electromechanical properties resulting from loss of lead oxide could be explained on the basis of the formation of a more titanate-rich solid solution, accompanied by the precipitation of zirconia"--Abstract, p. xv.
