Analysis of single and binary phases in cerium doped sodium bismuth titanate-inorganic materials Na0.5Bi(0.5-x)CexTiO3

The pure and cerium doped sodium bismuth titanate (NBT) inorganic powders were synthesized by solid-state reaction method. The presence of rhombohedral phase was observed in cerium doped NBT compounds. When x=0.05 of cerium doped NBT is heat treated at 1200 degrees C, the compound forms single perovskite phase. The samples of x = 0.10 and 0.15 were heat treated up to 1350 degrees C, the binary phases with cerium and bismuth oxides were observed. The X-ray diffraction, Fourier transform infrared spectroscopy, reflectance spectra, differential thermal analysis and thermogravimetric analysis were used to analyze the various properties of samples. Moreover, the effects of cerium doping and calcining temperature on NBT samples were investigated. In this work, we present our recent results on the synthesis and characterization of cerium doped sodium bismuth titanate materials. (C) 2015 SECV. Published by Elsevier Espana, S.L.U.
