Abstract

A pseudocubic-tetragonal-orthorhombic (PC-T-O) multi-structure was developed in the 0.96(K_0.5Na_0.47Li_0.03) (Nb_0.92Sb_0.08)O₃-0.04(Ca_0.5Sr_0.5)ZrO₃ [(KN_0.47L_0.03)NS-CSZ] lead-free piezoceramic. The PC structure observed in this sample was deemed to have an R3m rhombohedral structure. This sample demonstrated a large d₃₃ (560 pC/N) owing to the existence of the PC-T-O multi-structure. The (KN_0.47L_0.03)NS-CSZ thick film also exhibited a large d₃₃ (560 pC/N) and strain (0.19% at 4.0 kV/mm). The large strain was sustained even after the application of 10⁶ electric-field cycles. Therefore, the (KN_0.47L_0.03)NS-CSZ thick film exhibited excellent fatigue characteristics and was utilized to fabricate a planar-type actuator, which achieved a large displacement (300 μm) and acceleration (872 G) at 125 V/mm. A cantilever-type multilayer actuator was also prepared using five layers of the (KN_0.47L_0.03)NS-CSZ thick film and demonstrated a large displacement (3500 μm) and acceleration (42.96 G) at 250 V/mm. Therefore, the (KN_0.47L_0.03)NS-CSZ thick film is a good candidate for fabricating various piezoelectric actuators.
