• W91122009 abstract "Dielectric, ferroelectric and piezoelectric properties of perovskite lead-free ferroelectric ceramics such as BaTiO3 [BT], KNbO3 [KN], (Bi1/2Na1/2) TiO3 [BNT] and (Bi1/2 K1/2) TiO3 [BKT]-based ceramics and their solid solutions are described as superior candidates for lead-free piezoelectric ceramics to reduce environmental damage to the earth. Perovskite-type ceramics seem to be suitable for actuator and high power applications that require a large piezoelectric constant, d33 and a high Curie temperature, Tc, or a depolarization temperature, Td. The electromechanical coupling factor, k15 = 0.55, and the piezoelectric strain constant, d15 = 207 pC/N, are obtained at Mn-doped KN–Mn0.1 wt%. In the case of the BNT-based solid solution, x(Bi1/2Na1/2)TiO3-y(Bi1/2 K1/2) TiO3-zBaTiO3, [x + y + z = 1, y:z = 2:1, BNBK2:1(x)], the d33 values are 126, 181 and 80 pC/N for x = 0.78, 0.88 and 0.98, respectively. The depolarization temperature Td, rhombohedral-tetragonal phase transition temperature TR-T and the temperature Tm of the maximum dielectric constant were determined from the temperature dependence of the dielectric and piezoelectric properties. The three component solid solution, a(Bi1/2Na1/2) TiO3-b(Bi1/2Li1/2)TiO3-c(Bi1/2 K1/2)TiO3 [a + b + c = 1] (BNLKT100b-100c) has the morphotropic phase boundary (MPB) between rhombohedral and tetragonal phases at approximately c = 0.20. The piezoelectric properties are at maximum and the Td values show minimum near the MPB. The k33, d33 and Td of BNLKT4-20 and BNLKT8-20 were 0.603, 176 pC/N and 171 °C, and 0.590, 190 pC/N and 115 °C, respectively. On the other hand, the d33 and Td of BNLKT4-28 were 135 pC/N and 218 °C, respectively. Considering both high Td and high d33, the tetragonal compositions of BNLKT4-100z are thought to be a superior candidate. The high-power characteristics of BNLKT4-8Mn0.6 were superior to those of hard PZT at a vibration velocity v0-p > 0.6 m/s. The solid solution, (1-x)(Bi1/2 K1/2)TiO3– xBaTiO3 [BKT-BT100x], seems to be lead-free piezoelectric ceramics with wide operating temperatures. The BKT-BT100x ceramics (x = 0–0.4) indicated high depolarization temperatures, Td, around 300 °C. From these results, the BKT-BT system is a superior candidate as lead-free piezoelectric material for high power and/or high temperature applications." @default.
