PZT nanoparticles synthesized by sol-hydrothermal method and properties

  • 摘要: 结合溶胶-凝胶和水热法的优点,采用改进的溶胶-水热复合法在较低温下制备出纯相PZT纳米粉体,并对粉体的烧结性能进行了研究,分别讨论了烧结温度、保温时间等工艺参数对烧结陶瓷密度、微观结构和压电性能的影响.270℃保温热处理2h可合成出粒径约为20~30nm,具有良好分散性的钙钛矿型PZT纳米粉体,且具有良好的烧结活性.在1150℃烧结保温2h,压电性能达到最优(机电耦合系数: 0.50,机械品质因数: 410,压电常数: 220pC/N,介电常数: 1060).结果表明,溶胶水热复合法具有合成温度低、组分易于控制、粉体烧结活性高的优点.
