摘要： 研究了PMN-PT电致应变陶瓷材料的铌铁矿法制备及其电致应变性能,以及该陶瓷膜叠层型驱动器件的制备条件及性能.结果表明,0.94PMN-0.06PT陶瓷的应变迟滞最小;利用压延法可以提高叠层陶瓷膜的密度等特性;叠层型驱动器件的成型压力、预烧和烧结阶段的压力分别为200和0.01 MPa时,驱动器件的应变迟滞小于百分之一,并且驱动特性优异.

Abstract: PMN-PT electrostrictive ceramics were prepared by columbite method, and their electrostrictive properties were investigated. The conditions for preparing the stack actuator by ceramic thick films and its properties were investigated. The results showed that the strain hysteresis of 0.94PMN-0.06PT is the lowest. The stack ceramic thick films prepared by the rolling process have high densities and good properties. When the forming pressure and the pressure during calcining and sintering are 200 MPa and 0.01 MPa, respectively, for the fabrication of stack actuator, the strain hysteresis of 0.94PMN-0.06PT stack actuator is lower than 1% and the actuator has good working properties.
