Abstract: In this study, characteristics of (Bi0.5Na0.5)ZrO3 ceramic by using bismuth oxide as a sintering aid at appropriate sintering temperature were investigated. Phase characteristic of BNZ powder was checked by X-ray diffraction technique. It was found that BNZ powder has orthorhombically distorted perovskite (ABO3) structure. After that, BNZ/ᵪBi2O3 powders with ᵪ = 0, 0.5, 1, 1.5 and 2 wt% were pressed and sintered at 900°C for 2 h. Their X-ray diffraction patterns revealed that all produced a single phase perovskite phase. Microdtructure was investigated by scanning electron microscopy. It could be seen that un-modified BNZ ceramic composed a minimum relative density value. However, its microstructure evolution and relative densities were enhanced with increasing of Bi2O3 content. |
