  • Abstract:
  • Lead free piezoelectric ceramic composites (1-x) Na0.5Bi0.5TiO3-xSrTiO3 Where x=0.0-1.0 were prepared by sol-gel method. X-ray diffraction revealed the coexistence of Rhombohedral and cubic phases. This paper aims to explore the phase transition behaviour in lead-free ferroelectric materials using lattice distortion studies and Williamson-Hall (WH) plots to uncover the underlying mechanisms that influence material properties. The study will center on the use of X-ray diffraction (XRD) techniques to track changes in lattice parameters across different temperature-dependent and doping induced phase transitions. Lattice distortions, which are critical to the material's behavior, will be quantitatively analyzed to reveal how strain and crystallite size evolve during these transitions. The W-H plot of the XRD data enables separation of the strain and crystallite size contributions to the broadening of diffraction peaks.
