Influence of sintering temperature on structure, microstructure and piezoelectric properties of doped BZT–BCT ceramics
This work reports the influence of sintering temperature on structure, microstructure and piezoelectric properties of 0.48 Ba(Zr[Formula: see text]Ti[Formula: see text])O3–0.52 (Ba[Formula: see text]Ca[Formula: see text])TiO3(BZT–BCT) doped with ZnO nanoparticle ceramics manufactured by a conventional solid state reaction method. By increasing sintering temperature, the piezoelectric behaviors were improved and rose up to the best parameters at a sintering temperature of 1450[Formula: see text]C ([Formula: see text] pC/N and [Formula: see text]). The corresponding properties of undoped BZT–BCT ceramics were investigated as a comparison. The received results show that the sintering behavior and piezo-parameters of doped BZT–BCT samples are better than the undoped BZT–BCT samples at each sintering temperature.
