Abstract

We show in this work the usefulness of the polymeric precursors method to obtain several Ba(BIII2/3W1/3)O3 (B = In, Y, Dy, Gd, Sm) complex perovskites. Solid resins obtained from solution were treated at different temperatures and characterized by XRD and thermal analysis. BaCO3 and Ba(NO3)2 were the only crystalline species found below 500°C. Tungstates with different stoichiometry evolve from the powdered precursors as the temperature is raised. Formation of perovskite-like phases is evident in all five cases, above 1000°C. XRD results suggest also that trivalent ions do not participate in chemical reactions below that temperature since the presence of any binary phase containing them could be confirmed.
