A remarkable feature of these solid solutions is the \\emph{morphotropic phase boundary} (MPB), the composition across which the crystal symmetry changes. Critically, it has long been observed that the dielectric and piezoelectric as well as the ability to pole a ceramic increases dramatically at the MPB.
