Dielectric, ferroelectric, and piezoelectric properties of both random and textured Mn–PMN–PZT ceramics were characterized under uniaxial stress. Textured ceramics exhibit a large piezoelectric response under uniaxial pressure; the bias field piezoelectric constant is higher than 700?pC/N when pressure ...
However, it was later discovered for the case of ceramics that in the R-phase region the symmetry is actually lower. This is somewhat different than in Pb(Zr,Ti)O3 (PZT); however, to be noted is that also in the case of PZT short- and long-rage monoclinic phases were discovered and...
The electromechanical response of Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) and Pb(Mg1/3Nb2/3)O3-Pb(Zr,Ti)O3 (PMN-PZT) textured ceramics is evaluated. Results reveal that crystallographic texturing may enhance electromechanical performance without sacrificing mechanical robustness. The presence of grain...

textured PMN-PT ceramics fabricated by templated grain growth (TGG) show more than twice the piezoelectric response of conventional PZT-based ceramic materials, and show great promise for a large number of transducer applications. Over the past decade, numerous researchers have greatly advanced the ...
