      Accés restringit per política de l'editorial
      Polycrystalline powders of Ba1−xCaxBi4Ti4O15 (where x = 0, 0.25, 0.50, 0.75 and 1) were prepared via the conventional solid-state reaction route. X-ray diffraction (XRD) and Raman scattering techniques have been employed ...

    • Relaxor ferroelectric behavior and structural aspects of SrNaBi 2Nb 3O 12 ceramics 

      Kumar, Sunil; Ochoa Guerrero, Diego A.; García García, José Eduardo; Varma, K.B.R (2012-04)
      Article
      Accés restringit per política de l'editorial
      The SrNaBi2Nb3O12 (SNBN) powder was prepared via the conventional solid-state reaction method. X-ray structural studies confirmed the phase to be a three-layered member of the Aurivillius family of oxides. The SNBN ceramics ...
