Ferroelectric ceramic materials have a wide range of applications because of their piezoelectric and pyroelectric properties. One of their most important physical properties is the specific heat. In this study, the specific heats of a series of lead-zirconate-titanate (PZT) compositions in the vicinity of the morphotropic phase boundary (MPB) were measured. The temperature range was from 1.8 to 300...

Dense ceramics of 0.67Bi(Fe1-xTix)O3+x/2-0.33PbTiO3 (x=0, 0.005, 0.01, 0.02, 0.04) with MPB compositions have been synthesized by solid state reactions. Structural characterization by X-ray diffraction (XRD) reveals the simultaneous presence of a tetragonal, an orthorhombic, and a rhombohedral phases in 0.67BiFeO3-0.33PbTiO3. The electric conductivity decreases with the increasing Ti4+ substitution...
