Abstract

This study reports the effects of composition and the presence of residual template particles on the electromechanical properties of random and textured CuO-doped Pb(Yb_1/2Nb_1/2)O₃-Pb(Mg_1/3Nb_2/3)O₃-PbTiO₃ ceramics. Fully textured PYN-PMN-PT ceramics were produced with [001]-oriented barium titanate (BT) particles. The strain of all textured compositions was improved by 40–82 %, and the coercive field was increased by −1 kV/cm relative to ceramic compositions. Textured 20PYN-46PMN-34PT ceramics had the best combination of properties including a high E_c of 9.8 kV/cm and a low strain hysteresis of 8.5 %. Rayleigh analysis of textured PYN-PMN-PT ceramics showed that more rhombohedral compositions have greater strain because of improved extrinsic and intrinsic contributions to the piezoelectric response. These results demonstrate that textured PYN-PMN-PT is a promising material for high power transducers, however compositions must be sufficiently on the rhombohedral side of the morphotropic phase boundary to compensate for the phase-shifting effects of residual stresses from residual BT template particles.
