The PZT system (PbTixZr1−xO3, 0≤x≤1.0): High temperature X-ray diffraction studies. Complete x-T phase diagram of real solid solutions (Part 3)

The homogeneity regions of the real solid solutions contain phase-boundary lines of a new type evidencing of intraphase transitions prevailing in the rhombohedral phase, which show up in the presence of two and more different cell values (preserving the global crystal lattice symmetry).
