摘要：

In this review we address some of the experimental challenges found in the x-ray diffraction characterization of the low-symmetry phases recently discovered in the Pb(Zr1-xTix)O-3 (PZT), Pb(Zn1/3Nb2/3)(1-x)TixO3 (PZN-PT) and Pb(Mg1/3Nb2/3)(1-x)TiO3 (PMN-PT) piezoelectric systems around their morphotropic phase boundaries. In particular, we discuss the need for special care in the preparation of powder samples made from single crystals in order to avoid degradation and peak-broadening effects.
