Layered structure ferroelectrics received great attention because of their many applications in electronic devices as well as due to environmental concerns with Pb based materials. The SBTi (SrBi4Ti4O15) ceramics have attracted the attention for high frequency and high-temperature applications due to their high Curie temperature (Tc = 540oC). Obtaining nanoparticles in layered ferroelectrics is a challenging task. This book mainly deals with nanoparticles synthesis using microwave sintering and ball milling in bulk form and oriented nanostructure thin films through Radio Frequency Sputtering technique. Microwave dielectric and mechanical properties of the nanostructured bulk and thin films were discussed as an application point of view.
