Barium titanates is one of the most important ceramics that are widely used in the electronic industry because of its high dielectric constant, its ferroelectricity, and its piezoelectric properties. In the current study, five different batches of barium titanate powders were prepared by modifiedpechini method using the barium chloride and the titanium chloride as a starting materials in order to obtain different particle size distributions.SEM, TGA, DTA, XRD, FTIR, and other techniques have been used to characterize the prepared samples. XRD results suggested that the synthesized BaTiO3has a tetragonal phase.SEM images of the prepared samples reveala polyhedron shapes, on average, also it show that there are markedinfluence of the reactant concentration on the average size of the grains, where the samples prepared from higher solution concentration tend to possess larger grain size compared to that prepared from low concentration.
