چکیده
|
The study of the binary system (1-x) gd₂sn₂o₇ – x mo (m = mg and zn) shows new solid solutions with pyrochlore structure. they were synthesized using a conventional ceramic method and characterized by x-ray diffraction (xrd) and fourier transform infrared (ft-ir) absorption spectroscopy. the results showed that the resulting phases are new non stoichiometric solid solutions with the pyrochlore type structure in the compositional range 0 ≤ x ≤ 0,38 for m = mg and 0 ≤ x ≤ 0,43 for m = zn. the evolution of the lattice parameter, a, of these solid solutions decreases when the degree of substitution, x, increases in both series.
