摘要
Lead lanthanum zirconate stannate titanate (PLZST) based antiferroelectric to ferroelectric phase switching multilayer ceramic actuators were prepared by the tape casting method. The ceramic powders used were synthesized by a two-step wet chemical method using colloidal processing with a composition of Pb0.97La0.02(Zr0.65Sn0.25Ti0.10)O-3. The actuators sintered at 1100degreesC with Pd/Ag internal electrode and consisted of 20 active layer of 40mum thick. The strain behavior of the actuator were measured and a displacement up to 1.9 mum was achieved under 240V driving voltage.
