XRD patterns and SEM micrographs of random and textured 92BNT–6BT–2KNN ceramics.
(a) P–E hysteresis loops, S–P 2 curves, and (b) bipolar S(E) curves of textured and randomly oriented ceramic 92BNT–6BT–2KNN. (c) Lotgering factor F, electric-induced-strain and electrostrictive coefficient Q 33 as a function of BNT template content.
P–E hysteresis loops and bipolar S(E) curves of textured 92BNT–6BT–2KNN at (a) RT, various electric-fields, (b) 60 kV/cm, different temperatures. (c) S–P 2 curves of textured samples at different electric-fields and temperatures.
Electric-fields and temperature dependence of electrostrictive coefficient Q 33 for textured 92BNT–6BT–2KNN composition.
(a) Room-temperature electrostrictive coefficient Q 33 of lead-containing electrostrictors 2,23–25 and lead-free electrostrictors (textured 92BNT–6BT–2KNN in this work and other BNT-based ceramics 4–6,26,27 ), (b) variations of electrostrictive coefficient Q 33 with temperature for the studied textured 92BNT–6BT–2KNN and the traditional PMN ceramics. 2
