Abstract

ABSTRACT: A novel chemical route was used to produce nanosized BaTiO3 at 150°C without mineralizer. The well-defined peaks observed in Raman spectroscopy prove the presence of high quality tetragonal crystal-lattice-symmetry and are used to better understand mechanism of polarization-switching dynamics with molecular-vibrational modes present in the crystal-lattice. Rietveld refinement shows best fit for X-ray diffraction data with tetragonal symmetry. Nanosized BaTiO3 exhibits typical P-E hysteresis-loop and demonstrates ferroelectric nature. Dielectric measurements show Curie temperature at 130°C. These study guarantees that the novel chemical route can be used to synthesize other lead-free-ferroelectric-functional materials suitable for thinner dielectrics in higher-capacitance multilayer-capacitors.
