Abstract
Non-lead ceramic sample of Pr2Ti2O7 was prepared by standard high-temperature ceramic synthesis method. Rietveld refinements of X-ray diffraction data of the ceramic was carried out using FullProf software and determined their crystal symmetry, space group, and unit cell dimensions. Rietveld refinement revealed that Pr2Ti2O7 has a monoclinic structure with space group P 1 21 1. SEM study showed the formation of highly dense ceramic. The dielectric study displayed the two-phase transitions in the system in the investigated temperature range. Also, the phase transition temperature was found to frequency-dependent which suggested the relaxor-like behavior of the sample.
