摘要
摘要采用机械化学替代法成功合成了Bi4 - x La x Ti3O12 (BiLT, x = 0.60-1.00)陶瓷，并对其结构、微观结构、介电性能和铁电性能进行了研究。根据合成样品的热稳定性，将化合物在750℃下煅烧。在粉末x射线衍射图中未观察到二次相。扫描电镜下可见密度增强的片状。EDAX模式证实了样品的化学成分。制备的陶瓷样品在室温下具有相当可观的剩余极化值(≈14.5µC/cm2)。微观结构对改性BiT陶瓷的介电性能和铁电性能有显著影响。合成的化合物为创新的铁电基器件应用探索了理想的电子特性。
Effect of alternative mechanochemical method on modified bismuth titanate
Abstract Bi4 – x La x Ti3O12 (BiLT, x = 0.60–1.00) ceramics have been successfully synthesized by the alternative mechanochemical method and investigated their structural, microstructure, dielectric, and ferroelectric properties. Based on thermal stability of synthesized samples, compounds were calcined at 750 °C. No secondary phase is observed in the powder X-ray diffraction patterns. Plate-like shape with enhanced density is seen in the scanning electron microscope micrographs. EDAX pattern confirmed the chemical composition of samples. Prepared ceramic sample had relatively appreciable remanent polarization value (≈14.5 µC/cm2) at room temperature. Microstructure significantly influenced the dielectric and ferroelectric properties of the modified BiT ceramics. Synthesized compounds explored desirable electronic properties for innovative ferroelectric-based device applications.
