Abstract
Lead-free ceramic sample of Dy2Ti2O7 was prepared by standard high-temperature ceramic synthesis technique. 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 Dy2Ti2O7 has a cubic structure with space group Fd-3m. SEM study showed the formation of highly dense ceramic. No phase transition was displayed in the investigated temperature range from the dielectric study. The dielectric constant, as well as loss tangent values, were found, in general, to increase with the rise in temperature.
