Abstract

We synthesized grain-oriented lead-free piezoelectric materials in (K _0.5 Bi _0.5 TiO₃-BaTiO₃-Na_0.5 Bi_0.5 TiO₃ (KBT-BT-NBT) system with high degree of texturing along the [001]c (c-cubic) crystallographic orientation. We demonstrate giant field induced strain (∼0.48%) with an ultra-low hysteresis along with enhanced piezoelectric response (d 33 ∼ 190pC/N) and high temperature stability (∼160°C). Transmission electron microscopy (TEM) and piezoresponse force microscopy (PFM) results demonstrate smaller size highly ordered domain structure in grain-oriented specimen relative to the conventional polycrystalline ceramics. The grain oriented specimens exhibited a high degree of non-180° domain switching, in comparison to the randomly axed ones. These results indicate the effective solution to the lead-free piezoelectric materials.
