Abstract

The shear mode piezoelectric properties of Pb(Mg1/3Nb2/3)O3-Pb(Zr,Ti)O3 (PMN-PZT) ceramic with 72%<111> texture were investigated. The piezoelectric anisotropic factor d15/d33 was as high as 8.5 in<111> textured ceramic as compared to 2.0 in random counterpart. The high d15/d33 indicates the "rotator" ferroelectric characteristics of PMN-PZT system and suggests that the large shear piezoelectric response contributes towards the high longitudinal piezoelectric response (d33) in non-polar direction (d33=1100 pC/N in<001> textured ceramic vs. d33=112 pC/N in<111> textured ceramic).
