“…1 Lead zirconate titanate (PZT) piezoelectric ceramics are the most widely used amongst all kinds of practically applied piezoelectric ceramic materials. 2,3 However, at the sintering temperature of PZT ceramics of about 1200°C to 1300°C, 4 PbO will severely volatilize, leading to stoichiometric ratio deviation, performance degradation, and environmental pollution.…”

0.35Pb(Ni 1/3 Nb 2/3 )O 3 -0.65Pb(Zr 0.41 Ti 0.59 )O 3 (PNN-PZT) ceramics doped with 0.5PbO-0.5B 2 O 3 glass have been synthesized by the conventional solid-state sintering technique. The effects of 0.5PbO-0.5B 2 O 3 glass on the sintering temperature and piezoelectric properties of PNN-PZT ceramics were studied. The results indicated that the sintering temperature of PNN-PZT was significantly reduced due to the incorporation of 0.5PbO-0.5B 2 O 3 glass dopant. When the content of 0.5PbO-0.5B 2 O 3 glass was 0.5 wt.%, the sintering temperature of PNN-PZT was observed to reduce from above 1200°C to 920°C while the samples maintained high density (7.91 g/cm 3 ), excellent piezoelectric constant (d 33 = 479 pC/N), large electromechanical coupling coefficient (K p = 0.55), and relatively low electromechanical quality factor (Q m = 79). Moreover, large dielectric constant (e 33 T /e 0 = 2904) and low dielectric loss (tan d = 0.0166) were obtained in this work.

“…There is a great deal of interest in relaxor ferroelectric materials due to the rich diversity of their electrical/ physical properties and possible applications in various technological devices [1]. Diffuse phase transition and a strong frequency dependence of dielectric properties are the important characteristics of these materials, which are connected with their structural disorder and with the presence of polar nanodomains in non-polar matrix.…”

Measurement of thermal strain and total polarization estimation of lead zirconate titanate–lead zinc niobate ceramics

Thermal expansion properties have been measured for the ceramic lead zirconate titanate-lead zinc niobate [(1 -x)PZT-(x)PZN] in the temperature range of -100 to ?450°C. For all ceramics examined, the deviations from the straight line below Burns temperature were observed. The dynamic polarization fluctuations in their relaxor compositions are believed to play a role in this deviation. Burns temperature was determined and the local polarization (P d ) was calculated from the thermal expansion data. Various aspects of understanding the polarization behavior and other effects in this ferroelectric system were examined and discussed.

“…Piezoelectric materials have attracted much interest, both from fundamental and applied aspects, such as multiplayer ceramic actuator [1], transducer [2], sensor [3] and strain properties [4]. In recent years several compositions were investigated, the most interesting ones are Pb(Ni 1/3 Nb 2/3 )O 3 -Pb(ZrTi)O 3 (PNN-ZT) [5], Pb(Zn 1/3 Nb 2/3 )O 3 -Pb(ZrTi)O 3 (PZN-PZT) [6] and Pb(Mg 1/3 Nb 2/3 )-Pb(ZrTi)O 3 (PMN-PZT) [7].…”
