英文摘要Synthesis, characterisation and crystal structure analysis studies of oxides in (Gd2-xCex)Ti2O7 series have been reported, Ce3+ used as a surrogate for Pu3+ because they have similar physical and chemical properties. In the present report, a series of pyrochlore-type crystal with composition (Gd2-xCex)Ti2O7 (0 <= x <= 0.8) were successfully synthesised by the solution combustion followed by high temperature calcining. The phase purity and crystal structure of samples were investigated by X-ray diffraction analysis as well as Rietveld refinement. It was observed that the solubility of Ce3+ in the lattice of Gd2Ti2O7 pyrochlore is 39.62 mol.-%. The calculated lattice parameters and the simulated XRD patterns of (Gd2-xCex)Ti2O7 (x = 0, 0.5, 1) were obtained based on the density functional theory. The results of theoretical calculation are quite consistent with the results of the experiment. Additionally, the grain size and the visual information about the microscopic structure of the (Gd2-xCex)Ti2O7 crystals were obtained by transmission electron microscopy.
