Pure and cerium dioxide doped bismuth sodium potassium titanate (CeO2 doped BNKT) ceramics were synthesized by conventional method. CeO2 doped BNKT was prepared according to the composition Bi0.5(Na0.8K0.2)0.5TiO3x CeO2 where x = 0.1,0.2, 0.4, 0.6, 0.8 and 1.0 wt %. The heat treated powders were calcined from 800 to 900°C for 2 h. The samples were sintered from 1000 to 1100°C for 1 hr. The phase formation was confirmed by X-ray diffraction (XRD). The microstructures of the samples were analyzed by scanning electron microscope (SEM). It was observed that the there was a decrease in grain size with the increase in CeO2. Further, square pillar morphology was observed in the microstructures. The fourier transform infrared spectroscopy (FTIR) was used to investigate the phase evolution of compounds. The particle size measurement done for the sample (1 wt % CeO2 doped BNKT) using laser scattering particle size distribution analyzer revealed a particle size around 592 μm. © 2011, Sphinx Knowledge House.
