Preparation and Properties of B2O3-Doped Ba(Zr0.07Ti0.93)O3 Ceramics

In this work, barium zirconate titanate (Ba(Zr0.07Ti0.93)O-3) ferroelectric ceramics doped with B2O3 were prepared by the conventional mixed-oxide method. The properties of the ceramics as a function of sintering temperature were investigated. Various technique Such as X-ray diffraction (XRD) technique, scanning electron microscopy, dielectric permittivity spectroscopy and ferroelectric property measurement were used to obtain characteristic of the ceramics. The optimum density was observed for 1250 degrees C sintered sample. An increase ill sintering temperature produced a decrease in dielectric constant. However, ferroelectric behavior was improved in 1275 degrees C sintered sample. The results were discussed in term of microstructure and crystallinity of the ceramics.
