Lead-Barium-Titanate (PBT) ferroelectric ceramic has been synthesized by using solid state reaction technique with different sintering temperatures. Structure of the samples was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). XRD of the Pb-Ba-TiO3 samples confirms the tetragonal perovskite ferroelectric structure with lattice parameters in the range 3.94-3.987 Å and 4.068-4.22 Å, respectively. The grain growth increases with sintering temperature and the grain size of these samples is observed in the range 0.6-1.713 m from SEM analysis. The absorption bands around 575 cm – 1 to 585 cm – 1 are assigned to the stretching vibrations of Ti–O bonds from FTIR analysis. The crystallite size (D), lattice constant (a), microstrain (ε), and dislocation density (ρD) are also reported. The Williamson-Hall plot and size-strain plot are also employed to understand the structural and mechanical attributes of ferroelectric samples. Thus, we report variation of structural and mechanical properties of PBT with respect to sintering temperature. |
