The effect of CeO2 additions and methods of preparation on the microstructure of (Na0.5Bi0.5)TiO3, (NBT) have been investigated. NBT ceramics was prepared using solgel technique and then were doped with the CeO2 powders (0 0.4 wt%) using the solid state reaction method. The morphology and microstructure of the doped ceramics were investigated using SEM and XRD techniques, respectively. Based on the SEM images, the microstructure of ceramics remains unchanged with the additions of CeO2. However, the microstructure of the ceramics reduced in size significantly by using the sol-gel technique as compared to the solely conventional solid-state processes. While XRD patterns indicate that CeO2 with 0.1 0.3 wt% has diffused into the lattice of NBT ceramics.


Keywords: CeO2-doped NBT; microstructure; sol-gel
