Abstract

Strontium barium titanate, Sr_1−x Ba _x TiO₃ (BST) was prepared using tartrate precursor method. The X-ray diffraction patterns were used for analyzing the phase compositions. Lattice parameter, crystallite size, X-ray density, bulk density and porosity were calculated. The IR spectra confirm the results of X-ray for the formation of the perovskite structure. The surface morphology of BST at different barium content (x) was studied by scanning electron microscopy (SEM). The DC resistivity was studied as a function of temperature and the mechanism of conduction at different Ba content was established.
