ABSTRACT
Since the discovery of ferroelectricity in perovskite ceramic materials, there has been continuous development of materials and techniques to convert their advanced properties into novel technological applications. Barium titanate and strontium-doped barium titanate are excellent materials for microwave applications because of their high dielectric constant and very low dissipation factor. In this work, we review the dielectric and ferroelectric properties of BaTiO3 and barium strontium titanate highlighting the effect of Sr2+ doping. Various synthesis routes have been described. A brief discussion of the fundamentals of ferroelectricity and dielectric behavior of solids has been presented. Various microscopic techniques employed to provide a better insight into the properties of ferroelectric ceramic materials have been outlined. The potential of ferroelectric ceramic materials in integrated electronics as passive components and nonvolatile memory applications has been briefly discussed.
