High strain, <001>-textured Pb(Mg1/3Nb2/3)O3-Pb(Yb1/2Nb1/2)O3-PbTiO3 piezoelectric ceramics

Abstract

0.62[0.75(Pb(Mg1/3Nb2/3)O-3)-0.25(Pb(Yb1/2Nb1/2)O-3)]-0.38(PbTio(3)) ceramics were successfully textured in [001 1 (Lotgering factor of 0.91) using plate-like BaTiO3 templates, for the first time. Samples were densified to 98% of the theoretical density. Significantly higher levels of strain (0.33%) and low-field (<5 kV/cm) d(33) coefficient (1340 pm/V) together with a narrower hysteresis level (7.7%) at 50 kV/cm have been achieved in the textured ceramics. These results are very promising for high performance transducer and actuator applications without severe temperature restriction due to their higher T-c values (214 degrees C) and also open up new opportunities for the concept of domain engineering in the textured ceramics.
