Diffuse Scattering from Lead-Containing Ferroelectric Perovskite Oxides

Figure 3

Schematic phase diagram for PZT. The morphotropic phase boundary is noted, along with key structural phases. Temperatures and 𝑥 values for the various datasets discussed are noted on the figure—results at 577°C (850 K) are taken from [24], while letters (a), (b), and (c) correspond to diffraction patterns shown in Figure 4.
