利用微波烧结技术成功制备了高密度Ba0.80Pb0.20TiO3(BPT)陶瓷，这有助于减少传统技术中相当大的时间和能耗。 X 射线衍射 (XRD) 研究表明形成具有四方结构的单相。介电研究表明，与通过传统技术制备的样品观察到的结果相比，介电与温度关系图中出现尖峰，并且 Tcas 值较高。微波烧结技术极大地改善了压电性能。压电电荷系数“d33”为 157pC/N，而传统烧结样品的压电电荷系数为 130pC/N。
High density Ba0.80Pb0.20TiO3(BPT) ceramics were successfully prepared by using the microwave sintering technique, which helps in reduction of time and energy consumption that is quite large in normal conventional technique. X-ray Diffraction (XRD) study showed the single-phase formation with tetragonal structure. Dielectric study demonstrated sharp peak in dielectric versus temperature plots and high value of theTcas compared to that observed for samples prepared by conventional technique. The microwave sintering technique rendered drastic improvement in piezoelectric properties. The piezoelectric charge coefficient ‘d33’ was obtained to be 157pC/N as compared to 130pC/N in case of conventionally sintered sample respectively.
