Abstract
Nanosized barium cerate (BaCeO3) was prepared from barium cerium oxalate (BCO) precursor. Thermal decomposition of BCO precursor was studied using thermogravimetry(TG), differential thermal analysis (DTA), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) techniques. BCO precursor calcined at 1000°C for 2h gives nanosized BaCeO3 powder. Band gap of BaCeO3 was estimated using diffuse reflectance spectrophotometry and is found to be
2.17 eV. Particle size distribution study reveals that particle size of BaCeO3varies between 10-70 nm. Dielectric behavior of BaCeO3 was studied with varying the temperature at different frequencies. BaCeO3 shows good dielectric and conductivity response. Copyright © 2017 VBRI Press.
