“…Much attention has been given to various doping modification. It has been noted that addition of lithium element is an effective means enhancing the piezoelectric properties and lowing their sintering temperatures of ceramics [26][27][28]. Therefore, it can be reasonably expected that Na-doping may improve the properties of the BF-BT ceramics.…”

An enhancement in piezoelectric properties of lead-free ceramic materials by compositional engineering is often accompanied by a sacrifice in the temperaturestability of properties. Here we demonstrate that high piezoelectric properties and excellent high-temperature stability are obtained simultaneously in 0.72BiFeO 3 -0.28Ba 1-x Na x TiO 3 (BF-BTNx, x = 0-0.035) ceramics. Our results show that the high temperature-stable piezoelectric properties from 26 to 470°C, combined with room temperature high piezoelectric constant d 33 = 165pC/N and electromechanical coupling factor k p = 0.35 are achieved for x = 0.015 BF-BTNx ceramics. The results suggest Na-doped BF-BT system ceramic is a potential candidate for high temperature harsh environments actuators and sensors applications.

The present study proposes a 3-dimensional approach for enhancing the effective piezoelectric properties by poling orientation. The governing parameters for actuation and sensing applications are d 31 and d 31 ∕ 33 , respectively. The effective magnitudes of these parameters, i.e., d eff 31 and d eff 31 ∕ eff 33 , change with poling angles (roll and pitch angles). The combination of poling angles corresponding to the maximum magnitude of d eff 31 and d eff 31 ∕ eff 33 is called the optimum poling angle for piezoelectric materials. BaTiO 3 and KNN piezoelectric materials with tetragonal symmetry show an enhancement in d eff 31 ∕ eff 33 and d eff 31 at an optimized poling angle (roll angle). The piezoelectric material, 0.67Pb(Mg 1/3 Nb 2/3 )O 3 -0.33PbTiO 3 (PMN-0.33PT) with rhombohedral symmetry, shows a maximum improvement of 575% in d eff 31 ∕ eff 33at an optimum roll angle of 29° and a pitch angle of 60°. On the other hand, PMN-0.33PT shows an enhancement of 2034.44% in the d eff 31 coefficient at optimum roll and pitch angles of 50° and 60°. The effect of poling orientation on different piezoelectric materials with tetragonal and rhombohedral symmetry has been studied for actuation and sensing applications. The experimental approach to achieve inclination of dipoles through the placement of electrodes for different piezoelectric materials is also discussed.
