摘要

摘要: 作为重要的铁电陶瓷材料之一，PbZr_0.52Ti_0.48O₃(PZT)陶瓷因其广泛的工业应用而成为研究的焦点。通过水溶的溶胶-凝胶法，合成了PbZr_0.52Ti_0.48O₃陶瓷片。通过拉曼光谱测试技术结合高压实验，系统地研究了PZT(MPB-PZT：PbZr_0.52Ti_0.48O₃)陶瓷在不同压力下的拉曼光谱。拉曼光谱实验结果分析表明，在0~25 GPa的压力范围内，随着静水压力的增加，在压力为2.61 GPa时, PZT陶瓷发生了从三方-四方混合相到四方-立方混合相的结构相变，随着压力继续增大到8.5 GPa，PZT陶瓷完全相变为顺电立方相。同时，对PZT陶瓷片的介电常数进行了测试，确定PZT陶瓷片的居里温度为395 ℃。

Abstract: As one of the most important ferroelectric ceramic materials, PbZr_0.52Ti_0.48O₃ (PZT) ceramic has been widely studied because of its extensive industrial application.We prepared the PZT ceramic using a simple water-based sol-gel method, and studied its Raman spectra as a function of high pressure.Raman spectroscopy analysis show that the phase transition pressure from rhombohedral-tetragonal (R+T) to tetragonal-cubic (T+C) phases is 2.61 GPa and the pressure for T+C to C phase is 8.5 GPa.We also measured the dielectric constant of the PZT ceramic, the result suggests that the Curie temperature of the PZT ceramic is 395 ℃.
