On ordered perovskites with cationic vacancies. 2
Description
In Ba2Gdsub(0.67)vacantsub(0.33)UO6 a complete substitution of Usup(VI) by Nbsup(V) is possible by filling the cationic vacancies (x-phase: Ba2Gdsub(0.67+0.33x)Usub(1-x)Nbsub(x)O6). For the y-phase (Ba2Gdsub(0.67)Usub(1-y)Nbsub(y)Osub(6-0.5y) solid solutions are formed only for y <= 0.5. The properties of both phases are studied by x-ray and spectroscopic methods. In Ba2GdNbO6 - in contrary to the complete ordered Ba2GdTaO6 - the order of gadolinium and niobium is partial. (author)
