Enhanced dielectric and piezoelectric properties of xBaZrO3-(12x)BaTiO3 ceramics
xBaZrO3-(1!x)BaTiO3 solid solutions (x 1⁄4 0, 0.04, 0.06, 0.08, 0.12, and 0.18) synthesized via conventional solid state reaction method exhibit piezoelectric coefficients comparable to those of “hard” PZT-8, PZT-4, and even “soft” PZT-5A. Doping also improves the poling efficiency of xBaZrO3-(1!x)BaTiO3 ceramics. Study of temperature dependence of the dielectric and piezoelectric properties re...
متن کاملFerroelectric Heater by use of Pb(ZrTi)O3 and BaTiO3 Ceramics
A ferroelectric heater under A.C. field was demonstrated by using lead zirconate titanate and barium titanate ceramics. The temperature of the ceramics was increased from room temperature to its curie temperature of phase transition under an A.C. field. The heating characteristics greatly depend on the compositions of ceramics. It is proposed that the heating behavior is related to the domain s...
متن کاملMicrostructural and Dielectric Characterization of Sr doped Ba(Fe0.5Ta0.5)O3 Ceramics
----------------------------------------------------------ABSTRACT----------------------------------------------------------Solid state reaction method was used to synthesize Ba1-xSrx(Fe0.5Ta0.5)O3 ceramic(x=0, 0.1, 0.2, 0.3, 0.4 and 0.5). The raw materials of making Sr doped Ba(Fe0.5Ta0.5)O3 were BaCO3, SrCO3, Fe2O3, Ta2O5 (purity better than 99%). Pellet and ring shaped samples prepared from ...
متن کاملsoftening and hardening transitions in ferroelectric pb(zr,ti)o3 ceramics
Hysteretic and nonlinear dielectric behaviour in ferroelectric ceramics has been of interest since 1950s, when these materials found application in various electronic devices. Presently, these phenomena concern with important areas of science, technology and engineering. In particular, nonlinearity and hysteresis are the key factors in performance, precision and accuracy of modern devices. Many...
متن کاملRelaxor properties of Ba0.9Bi0.067(Ti1–xZrx)O3 ceramics
Starting from the well-known ferroelectric material BaTiO3, we show that coupled substitutions at the Ba and Ti cationic sites are able to improve the material properties. The compositions Ba0.9Bi0.067(Ti1−xZrx)O3 display a relaxor behaviour close to room temperature which open the way for possible use of it for capacitor applications. The origin of such optimization is related to the Bi cation...
