Wet chemical synthesis and investigations of structural and dielectric properties of BaTiO3 nanoparticles

In the present study, Barium Titanate (BaTiO3) nanoparticles were synthesized using one of the best route chemical method that is sol-gel auto combustion method. The structural and dielectric properties were investigated by powder X-ray diffraction (XRD), LCR meter and the results are reported herein. The phase purity and structural determination was carried by XRD technique at room temperature. The analysis of XRD patterns revealed of formation of single phase tetragonal structure. The lattice parameters 'a' and 'c' were obtained using XRD data and obtained lattice parameters matches with reported value. Average crystallite size was determined using Debye-Scherrer's formula and is found to be 6.4 Å indicating nanocrystalline nature. Dielectric properties like dielectric constant and dielectric loss tangent was investigated using LCR-Q meter method at varying frequencies. Both dielectric constant and dielectric loss tangent decreases with increasing frequencies. The PE characteristics and other studies are in progress.
