الوصف الكامل (Full Abstract)

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 modified pechini method using the barium chloride and the titanium chloride as a starting materials in order to obtain different particle size distributions. The SEM, TGA, DTA, XRD, FTIR, and other characterization techniques have been used to characterize the prepared samples. The XRD results suggested that the synthesized BaTiO3 has tetragonal phase. The SEM images of the prepared samples reveals a multi-faceted shape, on average, also it shows that there are marked influence of the reactant concentration on the average size of the grains. In which the samples prepared from higher solution concentration tend to possess larger grain size compared to that prepared from low concentration
