  1. The R-0BT, T-3BT, T-5BT, and T-7BT indicate random, 3 vol.% BT-textured, 5 vol.% BT-textured, and 7 vol.% BT-textured 0.19PIN–0.445PSN–0.365PT ceramics. The data of a commercially available “soft” PZT (PZT51, Yu Hai Electronic Ceramics Co., Ltd., China) ceramic and a PMN–0.28PT crystal was also given for comparison. k33: longitudinal-mode coupling factor; k31: lateral-mode coupling factor; kp: planar-mode coupling factor; kt: thickness-mode coupling factor. For each composition, five samples were used for the measurements of electromechanical properties and the standard errors were given in the table.
