The Strontium Bismuth Niobate SrBi2Nb2O9 (SBN), K0.025Sr0.95Gd0.025Bi2Nb2O9 (KSGBN1) and K0.05Sr0.9Gd0.05Bi2Nb2O9 (KSGBN2) ceramics were prepared by two stage solid state reaction method. Crystal structure of sintered samples was studied by powder X - ray diffraction technique. XRD patterns well matched with reported data (ICSD #82280). The lattice parameters of the samples were calculated using POWD Software. Pellets of 10mm diameter and thickness about 1mm similar to 2mm were prepared and final sintered in the temperature range 900 degrees C similar to 950 degrees C for four hours. The surface morphology of the samples was studied from Scanning electron Microscope pictures. The Temperature dependence of DC conductivity and dielectric properties were obtained and analyzed. Conclusions arrived at are presented. (C) 2018 Elsevier Ltd. All rights reserved.
